Hi,
I set a shortcut to filter chord symbols, but it doesn’t work. I don’t know why. I alway have to do it by clicking through the edit-menue, but that’s really annoying.
Would be happy to get help how to solve this. 
Thanks!
What OS are you using? What is the shortcut? What language is your keyboard set to?
Does the shortcut appear to be set in the Preferences? Does it appear in the Edit menu, alongside the command?
Have you restarted?
