NAME
sted - simple text editor demo program
SYNOPSIS
sted filename ...
DESCRIPTION
Sted is a simple text editor that illustrates the use of the
TextEditor and TextBuffer classes. Multiple files can be edited in
separate windows. Initially, windows are opened on each file
specified on the command line. Sted is not intended to be a
complete editor and cannot save modifications to a file.
EDITING MODEL
Sted implements a small subset of editing commands using an editing
model similar to emacs. Each window has a single text selection
that is displayed with reversed colors. If the selection is empty,
an insertion caret is displayed instead. Characters typed into a
window replace the current contents of the selection.
Currently defined commands include
quit
Close all windows and exit
close
Close this window
visit <filename>
Open a new window on filename
file <filename>
Edit filename in the current window
search <regexp>
Search forward for a match with the regular
expression regexp, wrapping from the end to the
beginning of the buffer if necessary.
goto <line>
Move the insertion point to the beginning of line
line, scrolling the display if necessary.
Commands are issued by clicking and typing in the 'minibuffer' at
the bottom of the window.
MOUSE BINDINGS
The left mouse button is used to select text. Clicking the left
button in the text window selects a new insertion point; Dragging
the button selects a range of text. If the mouse is dragged outside
the window, the display is scrolled to keep the selection point in
view.
The middle and right mouse buttons illustrate different ways of
scrolling with the mouse. Of course, scrolling can also be
performed using the scroller in the normal way. The middle mouse
button does 'grabber' scrolling. Clicking and dragging the middle
button causes the text to move along with the mouse. This scrolling
style is useful for fine control over small scrolling ranges. The
right mouse button does 'rate' scrolling. Clicking with the right
button and 'pulling back' on the mouse causes the text to scroll
upwards at a rate dependent on the position of the mouse. 'Pushing
forward' causes downwards scrolling. This style of scrolling is
useful for rapidly scanning through a large document.
KEYBOARD BINDINGS
For convenience, many operations can be performed from the keyboard.
These operations include scrolling, cursor movement, and command
execution. The current keyboard bindings mimic similar bindings in
standard emacs.
