** Keymap System
*** Keymap Stacking
There shouldn't be modes, there would be keymaps and a stack. Insert mode would
be at the bottom of the stack. Adding a new mode means pushing onto the stack,
and when a keybinding event is raised, you iterate over the stack from top to
bottom to find the correct keybinding. The vim nomenclature wouldn't work in
this case as you don't "leave insert mode". Rather, you pop the "normal mode"
keymap ontop of the "insert mode" keymap.
*** Passthrough/Blocking
The keymap object should have additional settings that dictate its behavior when
a key is found and not found.
**** Found
***** Pop
The default could be to pop from the stack.
***** Keep
Keep the keymap on the stack. This is useful for both normal mode and transient
like modes where you need to explicitly pop it from the stack.
**** Not found
***** Passthrough
Allow the loop to go to the next keymap
***** Block
Ignore missing key, don't pop the keymap, maybe report an error
