Custom keymaps

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

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

I'll implement an easier way in Preferences.

note

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