I bind F1 all the time, in the global map, and have done for over 20
years.  It selects the first created frame (which happens to be
conveniently called "F1" on a tty).  Likewise for F2 to F11.

Standard Emacs is strangely deficient in keyboard commands to select
frames.  C-x 5 o is unusably cumbersome if there are more than two or
three frames.
