The command palette listed select.key as Set Key Object. A pick runs
the command without an id, which cancels the key object (#541).
select.key is now labeled Cancel Key Object, the label of the Align
panel menu item that also cancels the key object. The palette lists
it once, and engine.commands reports the new label. The params text
and docs/mcp.md say that select.key {id} makes id the key object, and
that select.key {}, or an id that names no selected object, cancels
it. The Set Key Object rows are removed from the 10 catalogs that
had one.
Docs: the select.key params text, docs/mcp.md,
docs/target-app-parity.md.
