Local entry/exit: Enter/Escape
Direct entry/exit: s-<key>
- "Canonical Action":
- Each mode has a "canonical" action which is mapped to the same keybinding as direct entry (e.g. s-b s-b, or s-w s-w)
- Canonical action usually (always?) exits the mode
- E.g. window: "other window", buffer: flashback/"alt-tab", view: recenter, symex: evaluate
- "Format":
- Tab set to "preferred" (e.g. window: fit to width, view: preferred zoom, symex: indent)
- "Default":
- Backspace return settings to some notion of "default" (e.g. window: equal split, view: normal zoom)
The base (unmodified) keybindings set may include any higher-level keybindings (e.g. ? which would also fall under H-)
Simplicity over consistency.
Esc/Enter for higher/lower modes at a particular level
C-Esc/Enter for meta-level by level (base, mode, tower, ...) ["sideways"]
M-Esc to create a new ground and is otherwise equivalent to C-Esc ["vertically"]
s-Enter returns to (local) ground
H-Enter returns to absolute ground
