You'll need around 3000-5000 lines to get basic movement, undo, some
register handling, basic ex commands and visual mode to get a rough "vi

personally use...).

You'd probably need to put the machinery between GuiWorkArea::keyPressEvent()
and LyXFunc::processKeySym() and/or possibly replace LyXFunc::processKeySym().
