Yup.
It seems to only work for a few of them and while holding shift. I would prefer to handle it by just the function keys without having to also press shift/alt/cntrl
For what it's worth, the reason I never really got into creating 'shortcut keys', or started and then quickly stopped, is it just seemed like a non-starter for me. I realized that your typical end-user comes with shortcut keys all their own in the first place. They already have stuff in place. It will be stuff you don't (cannot) know about it going in. It could be anything from:
1) Google shortcut keys that conflict with yours
2) Desktop actual
shortcuts with a shortcut key combination that conflicts with yours
3) Some other program, where the designer also thought shortcut keys would be cool
...And the list goes on and on.
This is why generally speaking, shortcut keys in programs are only as good as the happy coincidence of that particular end user having no other conflicts with it at the present moment. It's like a shot in the dark, playing the lottery. They may work sometimes, not other times. Conflicting shortcut keys have various ways of behaving...from not working at all, to working some times, to working all the time for only one of the hosts. It's a mess.
IMHO.
