Changing notebook menu fonts?

Hi, How are the notebook menu fonts selected? Is this optional? Does it use the system wide font selections? Can it be changed? I’m talking about both the menu headings & the menu lists. Is there a notebook configuration file I can tweak? Running Linux Fedora.
thanks

I see that 109 people have read this but I’ve received no responses. Am I posting the question to the wrong place or does nobody know anything about notebook menu configuration?

There’s an answer to your question (or a similar question) about Linux menu size posted here: Solved: Linux Interface Toolbar and Font Size . I’m not a Linux user. If that solves your problem, please add a follow-up message here saying what you did. HTH.

I don’t know anything about Linux menus or how Mathematica interacts with them.

On Linux, you can customize it as needed by creating a custom stylesheet for Qt. More details can be found here.
