Find in Frame

[Doug]

I need to format all mentions of function keys (F1, F2...F11, F12)
with bold and enclose them in less than/greater than signs, such as
<F1>.  I also need to do this for the <Enter> key, and any other key
on a keyboard.

Is there a way to have Frame search for any instance of the capital
letter F that is located next to a number?  Using a simple wildcard
finds instances where F is next to a letter, such as FUBAR, so I need
something more than a simple wildcard.

Thanks,

Doug
