message KeyBinding

One shortcut the compositor takes before any client sees the key.

Read-only, and honestly so: these are compiled in. Listing them is worth doing on its own — a desktop whose shortcuts are only discoverable by reading its source is a desktop with no shortcuts, as far as most users are concerned — and the table this comes from is the same one the key handler dispatches through, so a listed binding is a binding that works.

action is a stable id ("workspace.switch"), meant for a settings app to key off; description is the sentence to show.
