SBE
---
SBE is a general-purpose text editor for modifying text files, such as .BAT
files and input files for compilers. SBE stands for Split-Buffer Editor, which
describes the internal representation of the text. One advantage to the
approach used is that the speed of entry of characters is not affected by file
size, as can be the case with other representations.
With SBE, you can load up to eight files in memory at one time, if you have
enough memory to do it. Each file is loaded into a buffer, and each buffer
uses 64K, no matter what the size of the file is.

Status line
-----------
This is the information found on SBE's status line:
+- The current buffer number, 0-7
| +- The file currently being edited, not including the path name
| | +- Insert mode/Overlay mode flag
| | |+- An '*' here indicates that the file has been changed

Cursor movement
---------------
These are the key combinations and the resultant cursor movements:
(Ctrl-key indicates that Ctrl should be held while pressing the second key).
Left - one character to the left
Ctrl-Left - one word to the left
Right - one character to the right
Ctrl-Right - one word to the right
Up - previous line in file
Down - next line in file
Home - first character of current line
Ctrl-Home - upper-left corner of screen
End - after last character of current line
Ctrl-End - lower-left corner of screen
PgUp - previous page of text
Ctrl-PgUp - beginning of file
PgDn - next page of text
Ctrl-PgDn - end of file

Other keys
----------
These are the other keys that SBE supports and what they do.
Del - deletes the character under the cursor
Ins - toggles insert/overlay modes
Backarrow - deletes the character to the left
Enter - ends the line and moves the cursor to the next line
Tab - moves the cursor to the next tab stop
Shift-Tab - moves the cursor to the previous tab stop

Deleting and Undeleting
-----------------------
Whenever you delete text using Ctrl-c, Ctrl-d, or Ctrl-w, the text is saved
in a buffer. If you delete more than once without moving the cursor, the
subsequent text is added to the previous text. For example, if you delete ten
adjacent lines using Ctrl-d, without moving the cursor, Ctrl-u will undelete
all ten lines as a block. This is an easy way to copy or move a few lines.
SBE saves up to ten buffers of code which you have deleted. You can select the
buffer before the current delete buffer by using Alt-u after a Ctrl-u. This
allows you to have more than one block of code which can be copied or moved.
Ctrl-c - deletes all characters from the cursor to the end of the line
Ctrl-w - deletes the next word
Ctrl-d - deletes the current line
Ctrl-u - undelete the text deleted by the previous Ctrl-c, Ctrl-d,
or Ctrl-w
Alt-u - re-deletes the text undeleted by Ctrl-u, and undeletes the text
deleted by the prior Ctrl-c, Ctrl-d, or Ctrl-w
