unable to get C-PGUP or C-PGDOWN key codes in tmux

Question

in order to configure vim I need to be able to know C-PGUP and C-PGDOWN keycodes.

what I usually do is

Ctrl-V Ctrl-PGUP 

or

Ctrl-V Ctrl-PG 

this gives something like

^[[5;5~

or

^[[6;5~

outside of tmux.

when doing the same in tmux, nothing happens wit Ctrl-PGUP or ctrl-PGDOWN... as if the terminal was just not detecting I pressed those keys (Ctrl-V works fine with other key combinations)

FYI, I am running tmux inside gnome-terminal (same problem with xterm... must be a tmux configuration issue...).

any help would be greatly appreciated

In your tmux.conf just add the following line:

set-window-option -g xterm-keys on
