Tucked away, the keys fold to ⋮, which turns gold while an assigned job is on, such as a tool, a lock, the torch or stabilization. MoviePro opens with the keys tucked away, and all three are empty until you assign them.

A dimmed key cannot be used now. The keys hide while the Focus rail, the zoom A/B panel, Presets, More or another menu is open, and in landscape while the tools menu or the scope view is open; they stay during a take. On a Remote controller they run the controller's own jobs.

Assign the jobs
- Open Settings › Interface Settings › Function Buttons, or tap an empty key on the camera screen to open its list.
- Tap F1, F2 or F3 and choose a job; the check mark moves to it. For Lens, choose the lens.
- Return to the camera. Reset to Defaults empties all three keys.
A job can be on one key only: a job already on another key is greyed, with that key's name. Change that key first.
Presets
A preset saves the three keys when you save or update it, and loading it brings them back; a preset saved without them leaves all three empty. While a loaded preset's keys are in use, the page header reads BUTTONS · FROM and the preset's name. Changes apply at once; update the preset to keep them. What a preset saves
