Custom keymaps

You can customize your keymaps, but it's not actually supported. If you want to mapjjasEsc, run the script below on the developer console.

CodeMirror
.
Vim
.
map
(
'
jj
'
, 
'
<
Esc
>
'
, 
'
insert
'
)

I'll implement an easier way inPreferences.

note

There's no way to share yank and clipboard for now.
