at times, I've accidentally hit Edit, Undo with the Mouse
problem is, I have no idea what I just un-did and how to find out?
this is especially annoying if machine has been up and running for several weeks and upon returning (from travel et al) I find that I've just selected Undo due to the slippery Mouse wheel/button
Go to Tools -> Output Window and then look at the Undo or Log tabs and you should find the answer.
If you find yourself hitting the menu item by mistake a lot you could always move it, or add a @confirm command to the button so it asks you if you are sure before doing anything.

I searched and read that thread before posting. How will this help when I reflexively press CTRL+Z?
To remove it go to Settings -> Customize -> Keys, find Ctrl-Z in the list and double-click it.
You will now be editing the Edit -> Undo menu item, which the Ctrl-Z hotkey comes from. You can clear the hotkey using the drop-down arrow on the right of the Hotkey field.
If you want to keep the hotkey and add the @confirm, click on the Advanced button (while still editing the Undo menu item) to open the multi-line editor. Then add @confirm to a line above the existing "Undo" line, as shown below.
(It's also possible to make @confirm display a particular message, e.g. "Are you sure you want to Undo?" instead of the generic message it will display by default. See the manual if you want to do that or shout if you need help.)
