When editing text, you can undo a change you made with Ctrl+Z; you can then apply the change again (undoing the undo) with Ctrl+Shift+Z; this is standard stuff. However, many users don't know the Ctrl+Shift+Z shortcut, and usually type "Ctrl+Y" to redo a change. It's the shortcut you see in the edit menu of Miscrosoft Word and LibreOffice Writer, for instance. That shortcut is also available in Firefox, Chrome, VsCode, Notepad++, etc. (Though I think most editors support both shortcuts.) Also, as far as I'm aware Ctrl+Y currently doesn't have a default assignation. As such, I think it would be worth assigning it as the alternate shortcut for the "Redo" command.

Would it make sense to add that to the standard shortcuts?
(In reply to Christoph Cullmann from comment #2) > Would it make sense to add that to the standard shortcuts? I think so, yes. "Ctrl-Y" is a shortcut a lot of people are used to.
That would be just copying Windows, which is not always a good idea. Ctrl+Shift+Z is more intuitive.
I should add that Ctrl+Shift+Z is the default shortcut to redo in LibreOffice, which, although not a KDE app, is what most distros ship as an office package.
There might have been a miscommunication. I'm not asking for the Ctrl+Shift+Z shortcut to be removed. I'm asking for both shortcuts to be supported by default. This is also the current behavior in LibreOffice, for instance.
