IIRC tmux looks for whatever they are set to in TERM. Use infocmp and look for eg kf11 etc

Subject: Re: Can we get Tmux to support more Function keys (F-keys) than just up to F20?
Is there a reference that shows what the escape key codes for those modified function keys (F13-F64) should be? Most terminal emulator applications don't really have good coverage of these key combinations, but e.g. iTerm for OS X does allow you to assign arbitrary escape sequences to key combinations.Â
So this means I should be able to get all 64 F-keys on iTerm as long as I go through and assign all the bindings, without having to set terminal-overrides.
Thanks

    F25-F36 are C-F1 to C-F12

  I have many traditionally unsupported key combinations that I would like
  to use which are not supported by traditional terminal emulators. I tend
  to use either a custom build of PuTTY on Windows or iTerm2 on OS X, which
  both allow me to send arbitrary byte patterns based on keystrokes. iTerm2
  is obviously easier to configure as it has a UI for this, for PuTTY I
  actually just hardcode them in.**
  Anyways, the only viable way that I've found so far to get these keys to
  work as custom tmux binds are to load them in as unused keys that tmux is
  designed to recognize. According to the manpage:**
  tmux allows a command to be bound to most keys, with or without a prefix
  key.** When specifying keys, most represent themselves (for example `A' to
  `Z').** Ctrl keys may be prefixed with `C-' or `^', and Alt (meta) with
  `M-'.** In addition, the following special key names are accepted: Up,
  Down, Left, Right, BSpace, BTab, DC (Delete), End, Enter, Escape, F1 to
  F20, Home, IC (Insert), NPage/PageDown/PgDn, PPage/PageUp/PgUp, Space, and
  Tab.
  Basically the only keys in this set that remain unused on a modern
  keyboard are the F13 thru F20 keys.**
  So far I have consumed 3 of these mappings (for various powerful caps lock
  key based shenanigans), but I am looking to add 4 more mappings (for being
  triggered by Alt+Shift+H/J/K/L -- as far as I can tell, key combinations
  like this as well as others like Ctrl+number keys, just aren't supported).
  At this point F14-F20 are used up and this leaves me with precious little
  left.**
  The way that I let tmux recognize my custom terminal codes is by using
  tmux's terminal-overrides option. Like this:**
  set -g terminal-overrides
  "*:kf20=\\033[34~,*:kf19=\\033[44~,*:kf18=\\033[54~"
  Now, when I look at the terminfo man page it lists a huge number of
  F-keys, up to F63 (and also including an F0 key). I think it would be
  awesome if tmux could somehow support this. I don't really need 52 extra
  function keys but only having 8 is not enough!
  Thanks
