I've been using Cntrl-Z for undo and right click for "Enter/SpaceBar" for a long time, and I made some changes to my menu files and they stopped working. I've tried to load old back ups and have tried everything I could find, but I can not get either one to work anymore. Control+Z is listed as an accelerator in my MNS for _u, at least I'm pretty sure the one I'm checking is the one that it is loading. Over the years my company has scattered back ups of the MNS all over the system and I'm not exactly sure which one is loading.
My support folder is the top on the list for for directories, and I'm editing the MNS in the support folder. Also, I can't remember how to set right click to the Spacebar or return key commands.
I am using R14.
