Problem with extended function keys in 1.9 (F13, etc)

[Matt Kowske]

Hello,

I recently upgraded from Ubuntu 14.04 LTS to 14.10 and seem to have lost
some functionality in tmux. 14.04 uses tmux 1.8 and 14.10 has 1.9, so I
am guessing that is the issue. I installed tmux 1.8 on my current ubuntu
14.10 machine and can verify that the functionality is back.

I am talking about the extended function keys. In 1.8 I can do
"send-keys F13" and get the appropriate F13 key sequence to be
interpreted by my terminal. In v 1.9 it simply sends the literal string
"F13". I am using identical an identical tmux.conf for both scenarios.
Is this a bug or something that I am missing? Is this possibly not
compiled into the Ubuntu 14.10 binary? Thanks!

For completeness, I did find a ticket related to this:

http://sourceforge.net/p/tmux/tickets/160/

Apparently F13 was changed to S-F1 in v1.9 so a key binding is no longer
neccessary. I confirmed I can just type "Shift + F1" on my standard
keyboard and F13 is sent.
