SEDT Reference Manual, Version 2.1
Interpreting keyboard input
Interpreting keyboard input
SEDT classifies all input into ASCII Characters, Function
Keys, Gold ASCII characters and Gold Function Keys. ASCII
characters are input through the normal typewriter keyboard,
using Ctrl to input control characters and Compose to input the
DEC Multinational characters. Function keys are input by hittinh
keys that are not part of the normal typewriter keyboard. Gold
ASCII characters and Gold Function Keys are input by typing PF1
-- sometimes colored gold on the keyboard -- before the ASCII
character or function key.
Printable ASCII characters and the space character are
inserted at the current cursor position in the file being edited.
Gold ASCII characters, control characters, gold control
characters, function keys and gold function keys are bound to
character strings. This is done at startup time by reading a
keyboard definition file or through commands that program keys.
Whenever a key is struck SEDT will insert the string that the key
is bound to into an internal command buffer.
Gold followed by a digit has a special meaning. SEDT
will interpret the digit and digits that immediatly follow it as
a count that will be applied to the next key to be struck. For
example, if you type Gold 1 2 a, a total of twelve character a's
will be inserted in the file. There are two exceptions to this
rule: the delete key will remove the last digit from the count
and control U will erase the count entirely.
Interpreting key definition strings
If a key definition string is terminated with a period it
is executed immediatly. If not, the string will be stored and
the string associated with the next key will be appended until a
string terminated by a period is encountered. Then the entire
string will be interpreted.
If a count was entered by typing gold followed by a
series of digits before a key the ascii representation of the
count will be inserted before the string associated with the key.
SEDT Reference Manual, Version 2.1
Interpreting keyboard input
Token replacement
Before the string is expanded it is scanned for ?, !, or
% characters. If any of these is followed by another of the same
one of the two will be removed, otherwise SEDT will respond as
follows:
? will cause SEDT to expect the following syntax:
?<delimiter><string><delimiter>
where <delimiter> is any ASCII character. SEDT will
display <string> on the bottom line of the display and
then accept input from the keyboard. Return, Enter or Do
will terminate keyboard input and the input from the
keyboard will replace the above construct in the command
string. Rubout will delete the character to the left of
the cursor. Control U will cancel the input and raise an
error condition that prevents interpretation of the
command string. Left and right arrows will move the
cursor to the left and right. ASCII characters will be
inserted at the cursor position. All gold characters and
function keys will cause the command string that is bound
to the key to be inserted at the cursor position.
! will cause SEDT to expect the following syntax:
!<delimiter><string><delimiter>
where <delimiter> is any ASCII character. SEDT will
display <string> on the bottom line of the display and
wait for a key or gold followed by a key to be struck. A
unique ASCII representation for the key will be inserted
in the command string instead of the above contruct.
% must be followed by one of the following characters: F
or N.
%F is replaced by the name of the output file of
the current buffer being edited.
%N is replaced by the name of the output file of
the current buffer being edited up to, but not
including, the first period.
Once the command string has been preprocessed it is
interpreted as a series of commands. The next chapter describes
all SEDT commands.
SEDT Reference Manual, Version 2.1
Interpreting keyboard input
If an error occurs during execution of a command string
commands following the one that the error occured in will be
skipped. Also, if the command was in a series of commands
enclosed in parentheses preceeded by a count the parentheses are
exited and further iterations skipped.
SEDT commands may be grouped by placing them in
parentheses. A count in front of a group of commands in
parentheses causes the group to be repeated the number of times
given in the count.
It is also possible to execute commands conditionally.
^C(<Commands>) causes <Commands) to be executed only if
the current buffer contains unsaved changes.
^C(<Commands>|<Commands>) causes the first group of
commands to be executed if the buffer contains unsaved
changes and the second group to executed if the buffer is
unchanged.
^E(<Commands>)(<Commands>) causes the first set of
commands to be executed. If any error occurs during the
execution the rest of the first string will be skipped
and the second group of commands will be executed. The
second command string is ignored if no error occurs.
^E(<Commands>)(<Commands>|<Commands>) will execute the
first group of commands. If an error occurs the rest of
the first command string will be skipped and then the
second group of commands will be executed, otherwise the
third set is executed after completion of the first
command string.
Basic Command Syntax
SEDT commands are alphanumeric trings preceeded by either
the letter <@> or the letter <:>. Commands preceeded by <@>
define a cursor position and normally move the cursor to the
position the command defines. Commands preceeded by <:> are
action commands that perform a change on the file being edited of
change the editing environment. Some action commands must be
followed by a position command that defines the range of text
that the command acts on.
SEDT Reference Manual, Version 2.1
Interpreting keyboard input
All commands can be preceeded by a direction indicator
and/or a count. Not all commands use the direction indicator or
count. Those that do have the direction indicator or count in
the syntactical description.
The direction indicator is one of <+>, <->, <<> and <>>.
<+> and <>> set the current direction to be forward, towards the
last character, in the buffer. <-> and <<> set the current
direction to be backward, towards the first character, in the
buffer. If no direction indicator is provided the command will
use the default direction which initially is forward but can be
changed with the commands :A and :B.
Count is either a string of decimal digits optionally
followed by a dollar sign <$> and another string of decimal
digits, or a dollar sign <$> followed by a string of decimal
digits. If no dollar sign is in the count, or it starts with a
dollar sign, it is interpreted as the decimal value defined by
the string. If the count contains a dollar sign between two
decimal strings it is interpreted at the decimal value defined by
the first string. If no count is given the command will use a
count of one.
$10 returns the count 10
20$30 returns the count 20
40 returns the count 40

current direction. The end of line is the
position to the immediate right of the last
character in the line.
SEDT Reference Manual, Version 2.1
Commands
@C
Character
Syntax: {+|-|<|>}{<Count>}@C
Semantics: Move the cursor <Count> characters in the current
direction. The end of line terminator is counted
as a character.
@F
Find
Syntax: {+|-|<|>}{<Count>}@F<Delimiter><String><Delimiter>
Semantics: Search for the <Count>'th occurrence of <String>
in the current direction and place the cursor

where the cursor was when a :M command with the
same count was executed last. Valid counts are 1
through 9. An error message is displayed if an
invalid count is given or a :M command has not
previously been executed with the same count.
SEDT Reference Manual, Version 2.1
Commands
@N
Next
Syntax: {+|-|<|>}{<Count>}@N
Semantics: Move the cursor to the <Count>'th occurrence in
the current direction of the string last given in
a @F command. The cursor is placed over the
first character of the string. The search is
case insensitive.

Semantics: Move the cursor to the first character after the
<Count>'th ASCII <FF> in the current direction.
If there are <Count>-1 ASCII <FF>'s in the
current direction the cursor will be placed at
the beginning of the file if the direction is
backward or at the end of the file if the
direction is forward.
@PAR
Paragraph
Syntax: {+|-|<|>}{<Count>}@PAR
Semantics: Move the cursor to the <Count>'th start of
paragraph in the current direction. If there are
exactly <Count>-1 beginning of paragraphs the
cursor will be placed at the beginning of the
file if the direction is backward or at the end
of the file if the direction is forward. A
beginning of paragraph is a sequence of ASCII
space, tab and line feeds containing at least two
line feeds. The cursor is placed on the first
character after the string of spaces, tabs and
line feeds.
SEDT Reference Manual, Version 2.1
Commands
@SEN
Sentence
Syntax: {+|-|<|>}{<Count>}@SEN
Semantics: Move to the <Count>'th start of sentence in the
current direction. A start of sentence is the
first character after a string of ASCII spaces,
tabs, line feeds, <.> and <;> containing exactly
one line feed, <.> or <;>. If there are exactly
<Count>-1 sentences the cursor will be placed at
the start of the file if the direction is
backwards or at the end of the file if the
direction is forward.
@SR
Select Range
Syntax: @SR
Semantics: Move the cursor to the point the cursor was at
the last time a :SEL command was executed. An
error message is displayed if a :SEL command has
not been executed.
@V
Vertical
Syntax: {+|-|<|>}{<Count>}@V
Semantics: Move the cursor <Count> lines in the current
direction. SEDT attempts to position the cursor
at the same column as the cursor was at before a
series of @V commands were issued. The cursor is
never placed further to the right than one column
to the right of the last character on a line. If
the line contains ASCII tab characters or
characters that SEDT represents with
multi-character sequences it may not be able to
position at exactly the same column.
A series of these commands will attempt to keep
the cursor at the column it was at when the first
command was executed.

Semantics: If the current buffer contains modified text the
user is asked whether the current contents should
be saved. If affermative, the contents are saved
in the current output file, otherwise the
contents are discarded. The contents of the
buffer are then cleared. The <File Name> argument
is assigned to the input filename and output
filename of the current buffer and the file is
read into the buffer if it exists. A new journal
file is opened. The cursor is placed at the
first character of the file.
SEDT Reference Manual, Version 2.1

Commands
:LD
Decrease indentation
Syntax: {<Count>}:LD
Semantics: Reduce the indentation level by <Count>, which
defaults to 1. The :TAB command moves the cursor
to the indentation level if the cursor is placed
to the left of the indentation level. The
indentation level is shown with an I on the ruler
display.
:LI
Increase indentation
Syntax: {<Count>}:LI
Semantics: Increase the indentation level by <Count>, which
defaults to 1. The :TAB command moves the cursor
to the indentation level if the cursor is placed
to the left of the indentation level. The
indentation level is shown with an I on the ruler
display.
:LK
Load key definition
Syntax: :LK<Key>
Semantics: Program the key given in <Key> to contain the
contents of the current buffer. See :K for the
valid codes for <Key>.
:LNE
Execute keystrokes stored in key
Syntax: {<Count>}:LNE<Key>
Semantics: Interpret the programming of the key defined by
<Key> as a sequence of keystrokes. The key is
assumed to have been programmed through the use
of the :LNL command. See :K for a description of
valid codes for <Key>.
SEDT Reference Manual, Version 2.1
Commands
:LNL
Store keystrokes in key
Syntax: :LNL<Key>
Semantics: Store subsequent keystrokes in the programming of
the key defined by <Key> until that key is
struck. The keystrokes are executed as they are
stored. The commands :LNL and :LNE are used to
store the keystrokes required to perform a
repeated task and then perform the task without
having to repeat the keystroke sequence. See :K
for a description of valid codes for <Key>.
The stored keystrokes are encoded as a code for
the class of the key followed by either an ASCII
character or a 3 digit ASCII value for the key.
Codes are:
A ASCII character
G Gold ASCII character
F Function key
B Gold function key
For printable ASCII characters, except digits,
the code is followed by the character. Otherwise
the code is followed by a 3 digit function key
number, see :K for valid values, or an ASCII
character value.
:LS
Set indentation level
Syntax: :LS
Semantics: Set the indentation level to the current cursor
position. The :TAB command moves the cursor to
the indentation level if the cursor is placed to
the left of the indentation level. The
indentation level is shown with an I on the ruler
display.
SEDT Reference Manual, Version 2.1
Commands
:M
Mark cursor position
Syntax: {<Count>}:M
Semantics: Store the current cursor position in one of 9
marks. <Count>, which defaults to 1, specifies
the mark to save the position in. Valid marks
are 1 through 9. As text is inserted and deleted
from the buffer marks are adjusted to point to
the same logical positions in the file.
:NL
New line
Syntax: {<Count>}:NL
Semantics: Insert a new line at the cursor position and
advance the cursor to the beginning of the new
line.
If the ruler line has automatic margin control
set the margin is set to the leftmost character
position not containing spaces and tabs in the
line the cursor was on. If the old line had only
spaces or tabs the automatic margin is set to
column 1. Finally insert spaces and tabs to
advance the cursor to the automatic margin just
defined. The result will be that left margins
will line up at any column position.
If a non-automatic left margin is set apces and
tabs are inserted to advence the cursor to the
left margin.
SEDT Reference Manual, Version 2.1
Commands
:NS
Substitute next
Syntax: {+|-|<|>}{<Count>}:NS
Semantics: Search in the current direction for the current
search string and if it is found replace the
ocurrence with the current substitute string. If
the cursor is placed on the first character of an
ocurrence the first substitution will be made on
that ocurrence. The current search string is set
with @F. :SL or :SUB. The current substitute
string is set with :SUB. The search is case
insensitive.
:OE
Output error message
Syntax: :OE<Delimiter><Message><Delimiter>
Semantics: Output <Message> exactly as an internal error
message from SEDT and perform the normal error
skipping of commands.
:OL
Open line
Syntax: {<Count>}:OL
Semantics: Insert <Count>, which defaults to 1, line feeds
after the current cursor position.
:OM
Output message
Syntax: :OM<Delimiter><Message><Delimiter>
Semantics: Output <Message> on the message line of the
display.
SEDT Reference Manual, Version 2.1
Commands
:OS
Toggle overstrike mode
Syntax: :OS
Semantics: Switch between insert and replace mode.
In insert mode typed input and characters
inserted with :I are inserted at the cursor
position and the cursor position is advanced,
thus pushing the text after the cursor in front
of it.
In replace mode the character at the cursor
position is replaced by the character being
inserted. If the cursor is at the end of the
line the character will be inserted rather than
replaced. If the cursor is at a tab character
the tab will be expanded to spaces before the
replacement takes place.
The current replace/insert mode is displayed on
the mode line of the display.
:PD
Insert current date
Syntax: :PD
Semantics: Insert the current system date in the format:
DD-MMM-YYYY. This command has no effect on
systems that do not maintain the current date.
:PL
Load paste buffer
Syntax: :PL<Delimiter><File name><Delimiter>
Semantics: Insert the contents of the file given in <File
name> in the paste buffer. This command is
normally used in conjunction with the :PS command
to preserve the contents of the paste buffer
across multiple sessions.
SEDT Reference Manual, Version 2.1
Commands
:PR
Print current buffer
Syntax: :PR<Delimiter><File name><Delimiter>
Semantics: Save the current buffer in the file given in
<File name>. After every 61 lines of output and
at the end of the file a form feed character is
inserted. If any character is typed on the
keyboard during the process the save will be
terminated.
:PS
Save paste buffer
Syntax: :PS<Delimiter><File name><Delimiter>
Semantics: Save the contents of the paste buffer in the file
given in <File name>. This command is normally
used in conjunction with :PL to preserve paste
buffers across multiple edit sessions.
:REP
Replace
Syntax: :REP
Semantics: If the last command was @F or @N remove the
occurrence found and insert it in the unknown
delete buffer. Then insert the contents of the
paste buffer.
:RF
Refresh display
Syntax: :RF
Semantics: Clear and reinitialize the display and rewrite
it. This command is used to recover from
corruption of the display.
SEDT Reference Manual, Version 2.1
Commands
:R
Ruler
Syntax: :R
Semantics: Switch into ruler definition mode. The cursor is
placed on the first character on the ruler
display in the second line of the screen.
Commands that affect the ruler are:
Right arrow Moves the cursor one character to
the right. The column number can
be read on the status line.
Left arrow Moves the cursor one column to
the left.
- Removes a tab stop at the current
position.
Tab Moves to next tab stop
Backspace Moves to column 1
T Inserts a tab stop at the current
position
L Sets the left margin to the
current position. When a Return
is entered the cursor will be
indented to the left margin.
R Sets the right margin to the
current position. If the right
margin is reached when entering
text, a new line will be entered
before the word being typed and
the word will be indented to the
word wrap margin.
J Sets the right margin to the
current position. If the right
margin is reached when entering
text, a new line will be entered
before the word being typed and
the word will be indented to the
word wrap margin after adjustment
of the text to the right margin.
SEDT Reference Manual, Version 2.1
Commands
W Sets the word wrap margin to the
current position. W fixes the
word wrap position.
A Sets automatic margin control.
The margin is always the leftmost
non-blank position on the current
line.
I Sets the indentation at the
current position.
Space Removes all formatting controls
at the current position.
Digit Load saved ruler number digit.
The rulers are saved in SEDT's
master directory under MS/DOS and
in the directory pointed to by
the logical name SEDT$Dir under
VMS. The name of the ruler file
is RulerN.Txt where N is the
number of the ruler.
Gold Digit Save current ruler in saved ruler
number digit.
Return Returns from ruler definition
mode to normal edit mode.
If more than one ruler setting is commonly used,
much time can be saved by storing the settings in
rulers 0 through 9. Ruler 0 is loaded by default
and any of the other rulers can be called up with
four key strokes: Gold R Digit Return.
The ruler line controls both left and right
margins. Several options exist for controlling
the margins.
No margin control is done if L, W, R and I are
set in column 1. Lines can be infinitely long
and the cursor is always positioned in column 1
after a Return is typed.
If L is set in a column different from 1 and W is
set in column 1 a Return will cause SEDT to
indent to the column defined by L.
SEDT Reference Manual, Version 2.1
Commands
If I is set in a column different from 1 and the
cursor is positioned to the left of the column a
Tab will indent to the column defined by I.
The left and right margin controls work as
follows:
W and R:
When a non-blank character is typed to
the right of R SEDT will insert a Return
in front of the first word that extends
to the right of R and indent to the W
column. The effect will be that text
will be filled between W and R. The fill
command, Gold Keypad 8 will fill text
from the current cursor position to the
end of the current paragraph. Text to
the left os W will be left unaffected.
W and J:
When a non-blank character is typed to
the right of J SEDT will change the
spacing between the current position and
W so that spacing after punctuation
characters will be exactly 2 and after
non-punctuation characters will be 1. A
return will then be inserted before the
first word that extends to the right of
J, after which spaces will be inserted
between words until the right margin is
justified to J. Finally the wrapped word
will be indented to W. Text to the left
of W will be left unaffected.
A and R:
When a non-blank character is inserted to
the right of R a return will be inserted
in front of the first word that extends
to the right of R. The text after the
return will be indented to the same level
as the line just terminated.

four key strokes: Gold R Digit Return.
The ruler line controls both left and right
margins. Several options exist for controlling
the margins.
No margin control is done if L, W, R and I are
set in column 1. Lines can be infinitely long
and the cursor is always positioned in column 1
after a Return is typed.
If L is set in a column different from 1 and W is
set in column 1 a Return will cause SEDT to
indent to the column defined by L.
SEDT Reference Manual, Version 2.1

If I is set in a column different from 1 and the
cursor is positioned to the left of the column a
Tab will indent to the column defined by I.
The left and right margin controls work as
follows:
W and R:
When a non-blank character is typed to
the right of R SEDT will insert a Return
in front of the first word that extends
to the right of R and indent to the W
column. The effect will be that text
will be filled between W and R. The fill
command, Gold Keypad 8 will fill text
from the current cursor position to the
end of the current paragraph. Text to
the left os W will be left unaffected.
W and J:
When a non-blank character is typed to
the right of J SEDT will change the
spacing between the current position and
W so that spacing after punctuation
characters will be exactly 2 and after
non-punctuation characters will be 1. A
return will then be inserted before the
first word that extends to the right of
J, after which spaces will be inserted
between words until the right margin is
justified to J. Finally the wrapped word
will be indented to W. Text to the left
of W will be left unaffected.
A and R:
When a non-blank character is inserted to
the right of R a return will be inserted
in front of the first word that extends
to the right of R. The text after the
return will be indented to the same level
as the line just terminated.
SEDT Reference Manual, Version 2.1
EDT style keyboard programming
A and J:
When a non-blank character is typed to
the right of J SEDT will change the
spacing between all words to the left of
the current position so that spacing
after punctuation characters will be
exactly 2 and after non-punctuation
characters will be 1. A return will then
be inserted before the first word that
extends to the right of J, after which
spaces will be inserted between words
until the right margin is justified to
the same level as the line just
terminated.
W to the right of, or at J/R:
No filling or justification will occur.
A to the right of or at J/R:
When a Return is typed the cursor will be
indented to the same level as the line
