Assign a keyboard shortcut to resetting history index?

[lphilpot]

Searching the forum I found several threads asking about "revert" (i.e., return to previously saved state) functionality, but no answers. I tried recording a macro to reset the history index, but Photo won't do that.

Is there any way to (directly or indirectly) assign a shortcut to the action of pulling the history slider back all the way leftward?

Thanks.

To directly answer this, there's no built-in shortcut to allow for this - you could of course hold down CTRL + Z (undo) until you reach the 'start' of your document, however depending on how much the file has been edited, this may take a considerable amount of time/computer resources.

However it sounds as though 'Snapshots' in Affinity Photo are essentially what you're looking for - although not tied to a keyboard shortcut, they allow you to 'jump' to a  specified 'step' in your History at any time, allowing you to compare the first image with the final product, for example.

You can find more information on Snapshots here -

I hope this helps

Yes, that would effectively do it from an editing viewpoint. Snapshots were mentioned in some of the previous posts I read. Assuming the Background snapshot always exists and there's a way to reliably and uniquely always select that snapshot from the restore menu, it could be macro-ed. But even so, the file itself will still have been changed. A true revert function just reloads the unsaved file.

I keep the history panel open so I can jump back at any time. I even find it useful when incrementally applying some effect (e.g., USM). I can apply it multiple times then walk back and forth through the history stack to find the best point. So I can just as easily push the history slider all the way back. I was thinking about a shortcut so it could be assigned to a button my tablet.

Thanks.
