I've tested on gnome-terminal of Fedora 19 GNU/Linux(without mouse).
It works fine! 

I'd like to report one thing I found during test.
pressing <f10> shows nothing if menu-bar-mode is off.
It is nice if menu-bar is shown temporary and automatically.

Here is a temporary solution. use your code only if 
menu-bar is shown.
