Lightroom Classic's keyboard shortcut page lists Command+Shift+K
(Ctrl+Shift+K on Windows) for Edit keywords, and its keyword help page
describes editing a keyword in Edit Keyword Tag from the Keyword List.
LightCraft had no key for it.
Edit Keywords (panel.editKeywords, Cmd+Shift+K) shows the Keywords
panel, opens its Keyword List when it is folded shut, and opens the
keyword picked in the list in Edit Keyword Tag. With no keyword picked,
or with the picked keyword deleted, it opens no dialog.
The command label has a row in every catalog. The KEYC-METADATA row,
docs/ui-parity.md and docs/library-shortcuts.md list the key. The
KEYC-METADATA row also lists the existing Alt+1 to Alt+9 keyword set
keys in place of "no keyword sets".
