"Shortcut is ambiguous" when defining certain ALT shortcuts
On kubuntu 18.04 with KDE5, certain default shortcuts do not work.
For example, ALT+2 is supposed to insert a note a second above. However, this conflicts with the menu entry for selecting 2nd voice from the note input bar. Similar problems happen for ALT+1-4 and others. Is there an option to disable the alt+letter shortcuts for menu entries altogether?
