TMUX key bindings

Question

Hi, I have a problem with TMUX key bindings. When I'm working on a terminal pane, if I press ctrl+pgup, it should scroll the screen one page up, as a normal terminal, but it doesn't.

Also, while using VIM, I have mapped to do some actions, but this key combination is not called.

Any TMUX expert there?.

Answer 1

Be sure that your shell and terminal are sending the appropriate escape sequences to one-another to indicate non-alphanumeric keys. For example, I use tmux with zsh in urxvt. I had quite a few problems with keys acting inappropriately (like enter insert mode and adding [3~) until I made sure my shell was communicating the appropriate key-bindings with:

# .zshrc
bindkey '\e[1~' beginning-of-line
bindkey '\e[4~' end-of-line
bindkey '\e[6~' down-line-or-search
bindkey '\e[5~' up-line-or-search
bindkey '\e[3~' delete-char

If this is your problem, yours are not likely to be the same, but you should be able to find resources specific to your shell and terminal emulator.

Answer 2

use the tmux command setw -g xterm-keys on

you may also need to add this to your ~/.vimrc

if &term == "screen"
    set t_kN=^[[6;*~
    set t_kP=^[[5;*~
endif
