Select CodeMirror Keymap¶
This extension lets you choose between the available CodeMirror keymaps: default, emacs, vim, and sublime.
There’s a chance that this might cause key conflicts, especially with other extensions.
Most browsers consume some of the global keybindings like
Ctrl+n. The Menu Wizard add-on for Firefox allows you to disable some of the global key shortcuts, thus passing the keys through to CodeMirror.
