IngestOpen Settings, then Shortcuts. Every command is listed with its key. Click the key and press the one you want. You can also Tab to the recorder and press Return or Space to begin. Esc cancels, and Delete removes the key so the command has none.
If the key is already taken by something that overlaps, Ingest names the other command and offers to move the key across. It refuses a key that is fixed, and it refuses the bare keys that move you around, because the app consumes those before any command sees them.
Standard Mac editing keys are reserved. Select All, Undo, Redo, and Settings retain their native shortcuts. If an older custom binding conflicts with a standard key, Settings explains the conflict and offers a reset; the saved override is kept until you change it.
While a text field has focus, ⌘A selects its text, and undo and redo stay in that editor. Photo-navigation keys do not intercept typing.
A changed key follows everywhere at once. The menus, the palette, the ? sheet, and the hold overlay all read from the same table, so there is no second place to update and nothing to get out of step. Reset All puts every key back.
