Interval shortcuts not working
After installing MuseScore2 on my new PCLinuxOS-KDE5-Plasma distro and while testing it,
I am facing the problem that the standard shortcuts for entering an interval do not work.
Navigating to Edit > Preferences and clicking on the Shortcut tab, the shortcut for several intervals
are there (for instance Alt+3 for a third), but nothing happens when I execute this shortcut in KDE5.
On my KDE4 desktop where I do not have this problem, I see no difference when I compare the shortcut list between KDE5 and KDE4.
What did I forgot to do to get things working in KDE5?
