Short description of error
The shortcut for undo history has been removed and when I right click on the action I am not given the option to add my own shortcut, I con add add to quick favorites . This is something I used almost more than ctl-z to ensure I was undoing what I wanted to on an system intensive operation.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
