Some time ago I set up the keyboard shortcut alt-L for"insertmate".  Some time later, I realized that,insketches, I can't use the standard shortcut alt-L to make twolinescollinear, because I've reassigned that shortcut.  So Iwrotea new shortcut, shift-L, for "insert mate", and deleted(orremoved) the alt-L shortcut.  But in every new sessionofSolidworks, both shortcuts for "insert mate" show up, andalt-Ldoesn't work for collinear relations ... unless I re-removethecustom shortcut, and then only for the remainder of thatsession.

How do I remove a custom keyboard shortcut and KEEP itremoved? TIA ...SolidworksUser Interface
