----------------------Emacs key bindings---------------------
|
||
|
|
This CodeInput inherits from EmacsBehavior, so you can use Emacs key bindings
|
||
|
|
if you want! To try out Emacs key bindings, set the "Key bindings" option to
|
||
|
|
"Emacs". Experiment with the shortcuts below on some of the text in this window
|
||
|
|
(just be careful not to delete the cheat sheet before you have made note of the
|
||
|
|
commands!)
|
||
|
|
|
