You can use the `editor` program to edit files. The editor itself is fairly
|
||||
simple to use. It currently supports these keyboard commands:
|
||||
|
||||
* `Ctrl-Q` - Exit
|
||||
* `Ctrl-O` - Open a file
|
||||
* `Ctrl-S` - Save a file
|
||||
* `Ctrl-C` - Copy
|
||||
* `Ctrl-I` - Go to line
|
||||
* `ESC tabsize <desired-tab-size>` - change tab size
|
||||
* `Ctrl-K` - Cut
|
||||
* `Ctrl-O` - Open a file
|
||||
* `Ctrl-Q` - Exit
|
||||
* `Ctrl-S` - Save a file
|
||||
* `Ctrl-V` - Paste
|
||||
* `Ctrl-X` - Cut
|
||||
* `ESC language <c or c++>` - enable syntax highlighting
|
||||
* `ESC margin <column>` - add right margin at column
|
||||
* `ESC popen <command>` - open command output
|
||||
* `ESC language <c or c++>` - enable syntax highlighting
|
||||
* `ESC tabsize <desired-tab-size>` - change tab size
|
||||
|
||||
It is not currently possible to port third party editors because the terminal
|
||||
implementation is not standards-compliant enough and is seriously lacking.
