Scope of plugin shortcuts

Hello,

I wrote my own "toggle visibility" plugin, so I removed the shortcut for that action in preferences->shortcuts, and defined V as the shortcut for my plugin.

That works, but when I'm entering text, I can't type the letter 'v' anymore.

So musescore is treating shortcuts differently. Is there a method to set the 'scope' of a shortcut?
And if not, is there a method to find out if you are in 'text mode' and if so, is it possible to insert
a letter at the text cursor's position? If so, I can do this in my plugin.
It would hardcode the shortcut in my plugin code, which is kind of ugly, but I can live with that.

Thanks,
Luc.

PS. I know I can choose a key-combination that isn't used in text as shortcut, so that's not the issue :-).
