Add, "How to Change the Default Menubar Font Size"
Took me a little while to figure out. The toughest part was finding the default menubar GUI style was named Anthrax, which was odd.

For those using bigger monitors, such as Dell U2713HM providing higher resolutions, I find it necessary to increase the font of the menubar. (Especially while browsing the Internal variables!)
"File > Reset", or restart FlightGear as the "Debug > Reload*" options won't reload the font size of the menubar.
Helvetica fonts doesn't seem to provide fonts larger than the size of 18 here on my Linux box, so specifying a higher size will only revert to the default font size.
