Ctrl keys in NeoVintageous are enabled by default. You can toggle them via the Command Palette NeoVintageous: Toggle CTRL keys.

The key notation in Vim in <C-...> e.g. <C-l>.

Case Sensitivity

In Vim, <D-A> and <D-a> are equal i.e. the case of {char} in <D-{char}> doesn’t matter. But in Sublime Text all the keys are case-sensitive, using the shift key produces different key events. The advantage is that, unlike Vim, in Sublime Text you can create mappings for both <D-A> and <D-a>.

Key Handler

You can configure the key handler to ignore selected keys. Read the NeoVintageous Key Handler.
