# NAME
|
||
|
||
ke – Kyle's text editor.
|
||
|
||
## SYNPOSIS
|
||
|
||
ke \[files\]
|
||
|
||
## DESCRIPTION
|
||
|
||
ke is Kyle's text editor and is probably ill-suited to
|
||
everyone else. It was inspired by Antirez' kilo text editor by way of
|
||
someone's writeup of the process of writing a text editor from scratch.
|
||
It has keybindings inspired by VDE (and the Wordstar family) and emacs;
|
||
its spiritual parent is mg(1).
|
||
|
||
## KEYBINDINGS
|
||
|
||
K-command mode is entered using C-k. This is taken from
|
||
Wordstar and just so happens to be blessed with starting with a most
|
||
excellent letter of grandeur. Many commands work with and without
|
||
control; for example, saving a file can be done with either C-k s or C-k
|
||
C-s. Other commands work with ESC or CTRL.
|
||
|
||
## K-COMMANDS
|
||
|
||
k-command mode can be exited with ESC or C-g.
|
||
|
||
* C-k BACKSPACE: Delete from the cursor to the beginning of the line.
|
||
* C-k SPACE: Toggle the mark.
|
||
* C-k -: If the mark is set, unindent the region.
|
||
* C-k =: If the mark is set, indent the region.
|
||
* C-k a: Set the mark at the beginning of the file, then jump to the end of
|
||
the file.
|
||
* C-k b: Switch to a buffer.
|
||
* C-k c: Close the current buffer. If no other buffers are open, an empty
|
||
buffer will be opened. To exit, use C-k q.
|
||
* C-k d: Delete from the cursor to the end of the line.
|
||
* C-k C-d: Delete the entire line.
|
||
* C-k e: Edit a new file.
|
||
* C-k f: Flush the kill ring.
|
||
* C-k g: Go to a specific line.
|
||
* C-k j: Jump to the mark.
|
||
* C-k l: Reload the current buffer from disk.
|
||
* C-k m: Run make(1), reporting success or failure.
|
||
* C-k p: Switch to the next buffer.
|
||
* C-k q: Exit the editor. If the file has unsaved changes, a warning will
|
||
be printed; a second C-k q will exit.
|
||
* C-k C-q: Immediately exit the editor.
|
||
* C-k l: Reload the current buffer from disk.
|
||
* C-k s: Save the file, prompting for a filename if needed.
|
||
* C-k u: Undo.
|
||
* C-k r: Redo changes.
|
||
* C-k x: save the file and exit. Also C-k C-x.
|
||
* C-k y: Yank the kill ring.
|
||
* C-k \\: Dump core.
|
||
|
||
## OTHER KEYBINDINGS
|
||
|
||
* C-g: In general, C-g cancels an operation.
|
||
* C-l: Refresh the display.
|
||
* C-r: Regex search.
|
||
* C-s: Incremental find.
|
||
* C-u: Universal argument. C-u followed by numbers will repeat an operation
|
||
n times.
|
||
* C-w: Kill the region if the mark is set.
|
||
* C-y: Yank the kill ring.
|
||
* ESC BACKSPACE: Delete the previous word.
|
||
* ESC b: Move to the previous word.
|
||
* ESC d: Delete the next word.
|
||
* ESC f: Move to the next word.
|
||
* ESC q: Reflow the paragraph to 72 columns or the value of the universal
|
||
argument.
|
||
* ESC w: Save the region (if the mark is set) to the kill ring.
|
||
|
||
## FIND
|
||
|
||
The find operation is an incremental search. The up or left arrow
|
||
keys will go to the previous result, while the down or right arrow keys
|
||
will go to the next result. Unfortunately, the search starts from the
|
||
top of the file each time. This is a known bug.
