Re: How to bind isearch-repeat-forward to F3 in a certain mode only?

The key <F3> is represented by the symbol `f3' in Emacs, that's it.  I
think it's by convention because all event basic types are represented
by lower case symbols.  Unlike in Common Lisp, in Emacs Lisp symbol
names are case sensitive.

That (kbd "<F3>") doesn't return what could be expected is not nice,
OTOH it's just consistent.

That would not harm (would it?), though avoiding it would be cleaner.

No.

If the bindings are not directly related to your mode, you should not
put it into its hook.

But be careful: changing the major mode in any buffer kills all buffer
local variable bindings.
