I am attempting to create a keyboard menu item shortcut using control + m. I have been successful at doing this however, I'm running into problems with this particular shortcut as it works about half the time.
Upon further inspection I discovered that control+m seems to already have an assignment. It insert a new row in a matrix. I don't see control+m in the keyeventtranslations.tr file and there is no mention of this shortcut anywhere in wolfram documentation. As far as I can tell, it should be unassigned. Did I create this accidentally in the past? Can you verify on your mac if this shortcut is active on your machine?
If I did pick it up somewhere, do you have any suggestions on where I can look for this so I can change or delete it? It's not in my keyeventtranslation.tr file and I don't see it in my init.m file. I have tried restarting mathematica. No luck.
