Arrow Up shortcut issue

[franc]

Hellow

I have 3.0.3 (64-Bit) on MacBook Pro (Mid 2009) and I set the "Medium forward jump" Hotkey to the arrow-up-key.
Also I set the "Long forward jump" to ctrl+ARROWUP.
This works only if I (left-mouse-) click once in the VLC-Window (when a movie is running) somewhere. Only after this the long jump forward works with Arrow Up Key.
If I dont initially click, I get an error noise when I push the Arrow-Up-Key, nothing jumps. Neither the Long forward jump with ctrl.
It works without click, if I set another Hotkey to the jump, only the Arrow-Up is the issue.

Is this by design or just a bug?

Thanks
