Your F21 key might not issue the <f21> key event.  To know what
that key issues, evaluate[1] the Lisp form `(read-event)' in the
*scratch* buffer and type the F21 key.  What is observed in your
Emacs?

[1] Put the line `(read-event)' into the *scratch* buffer (don't
include the quotation marks) and type C-j at the end of the form.
