====== Edit tab w/CodeMirror Keyboard Mapping ======

AstLinux now supports the versatile [[https://codemirror.net/|CodeMirror]] text editor, implemented in JavaScript for the browser.  CodeMirror is now the default text editor within the AstLinux web interface **Edit tab**, but users may still use the standard HTML editor if they choose.

!!Note: AstLinux 1.3.7 or later is required!!

New options can be found under the **Prefs tab** -> Edit tab Options:

Unchecking "CodeMirror Editor" will revert back to using the standard HTML editor.

The user may select a "Theme", the [default] is colored text on a white background.

!!Tip ->!! Themes [solarized], [seti-mks] and [zenburn] are worth a look.

**AstLinux Specific Keyboard Mapping**

__Toggle Fullscreen__  -> ''Tab''

Fullscreen mode will make the text editing area use the full current window.  ''Tab'' will toggle between the two states, very handy.\\ 
To insert a ''Tab'' (for spacing) within the editor window, you need to type ''Ctrl-Alt-Tab'' (on a Mac).

__Exit Fullscreen__  -> ''Esc''

The natural key choice to return to normal mode.  Only applies when in fullscreen mode.

__Toggle Comment__  -> ''Ctrl-/'' or ''Ctrl-.'' (PC), ''Cmd-/'' or ''Cmd-.'' (Mac)

Comment or un-comment the selected line(s) depending on the current comment state.
