Undo-Redo Commands & History Panel Options

[Mark_Weidman]

I recently had to Reset Preferences in Photoshop v25.12.0 to fix an unrelated problem.  Running OSX v14.7 on an Apple Mac. Before Resetting Prefs, I used to be able to toggle back & forth between actions simply using Command-Z.  That no longer works, I have to use Command-Shift-Z, which I find cumbersome.  I could not find anything in Settings to change this.  Suggestions welcome.

Secondly, a new problem with the History Panel.  When I Open History Options and check “Show New Snapshot Dialog by Default”, this function does not work, I do not get a New Snapshot Dialog.

If you check the menu (Edit > Undo and Edit > Redo), do they show these different keyboard shortcuts? Or just one (Cmd+Z)

Above is a screen shot of the Edit Menu where you can see both Undo & Redo. Is there any way to remove the Redo and use only Command Z for both Undo & Redo? That is the set up on my laptop (Powerbook) running the same version of PS as on my Mac Pro.

Edit->Keyboard Shortcuts.

Try checking/unchecking Use Legacy Undo Shortcuts

[Mark_Weidman]

Success! Checking Use Legacy Undo Shortcuts works perfectly. Thanks very much.

The second problem persists in that the History Options does not allow me to create a new dialog box when creating a new History log.

Thanks Lumigraphics for the fix to my Undo Command problem.  I still have not found a fix for the second problem, with the History Options panel.  Even when checked, "Show New Snapshot Dialog by Default", does not work  I have Reset Preferences three times; still not working.  Any suggestions are welcome!
