While you're editing a slide in DIGIDECK, undo lets you step back through your recent changes and reverse them one at a time. It's the safety net for the small mistakes that happen constantly while you build — a component you nudged too far, text you overwrote, a color you didn't mean to change.
How to undo
Undo uses the same keyboard shortcut you already know from every other app:
Mac:
Cmd + ZWindows:
Ctrl + ZAdd shift to "redo"
Each press reverses your most recent action. Press it again to step back another change, and again to keep going, walking backward through your edit history on that slide.
Undo works one slide at a time
Undo in DIGIDECK is scoped to the slide you're actively editing. Every slide maintains its own independent undo history while you have it open. When you make changes to a slide, those changes are tracked for that slide only — undoing on it won't touch anything on your other slides, and their edits won't show up in its history.
This keeps undo predictable: whatever you press Cmd + Z / Ctrl + Z on, you're only ever reversing changes to the slide currently in front of you.
Leaving a slide clears it's undo history
This is the most important thing to know about how undo behaves.
A slide's undo history only lives while you're on that slide. The moment you navigate away — to another slide, or out of the editor — that slide's undo memory is cleared. When you come back to it later, you start with a clean slate: the earlier changes are still saved to the slide, but they're no longer reversible with undo.
In practice, that means:
Undo is a live, in-the-moment tool, not a permanent history of everything you've ever done to a slide. (That is slide history)
If you want to reverse something, do it before you move to another slide.
Once you've navigated away, treat the changes on that slide as committed.
