I just loaded beta 2. If I start beta 2 with a new config directory (so it doesn't try to upgrade my 18.0.1 config), the top level menu hot-keys are all set. Tools has a hot-key of T but in my 18.0.1 version, it has a hot-key of 'o' instead ... I don't think I intentionally changed it, but T makes more sense so I don't particularly care.
But if I allow beta 2 to upgrade my 18.0.1 configuration, then the View and Tools menus do NOT have a hot key set, but all the others do. If I go and edit the _mdi_menu and add a hot-key of V and T respectively and save, the View menu now has a hot key of 'i' while the Tools menu still has no hot key. Should I attach any specific 18.0.1 config file to help debug?
