Minor modes

These sub-modes are accessible from normal mode and typically switch back to normal mode after a command.

View mode

View mode is intended for scrolling and manipulating the view without changing the selection. The "sticky" variant of this mode is persistent; use the Escape key to return to normal mode after usage (useful when you're simply looking over text and not actively editing it).

i <object>	Select inside textobject	select_textobject_inner

TODO: Mappings for selecting syntax nodes (a superset of [).

Window mode

This layer is similar to vim keybindings as kakoune does not support window.

Key	Description	Command
w, Ctrl-w	Switch to next window	rotate_view

Space mode

This layer is a kludge of mappings, mostly pickers.

f	Open file picker	file_picker
b	Open buffer picker	buffer_picker
s	Open symbol picker (current document)	symbol_picker

R	Replace selections by clipboard contents	replace_selections_with_clipboard

Insert Mode

Key	Description	Command
Escape	Switch to normal mode	normal_mode

Select / extend mode

I'm still pondering whether to keep this mode or not. It changes movement commands (including goto) to extend the existing selection instead of replacing it.

NOTE: It's a bit confusing at the moment because extend hasn't been implemented for all movement commands yet.
