tmux and vim configuration

Posted on Sep 9, 2010

I’ve now been on tmux for quite a few months since migrating from screen.

aterm + tmux + zsh + vim makes a super command-line combination.

But there can be certain issues with the key bindings with vim. Since moving to tmux I’ve avoided using vim tabs since I couldn’t figure out the right key bindings to switch them using C-PgUp and C-PgDn when in tmux. But today with a little help on #tmux and kerneltrap I finally got things working. So here are my .tmux and .vimrc files for posterity.

# start a new session on tmux att if no existing session is running new  # screen prefix key set -g prefix C-a  # large history set-option -g history-limit 100000  # swap on C-a C-a bind-key C-a last-window bind-key k confirm-before kill-window bind-key r source-file ~/.tmux.conf bind-key v split-window -h #similar to vim's vsplit bind-key h split-window  set-option -g default-terminal "screen-256color"  # status bar customisation set-option -g status-bg default set-option -g status-fg green  # highlight status bar on activity set -g visual-activity on  # change foreground-background for the current window setw -g window-status-current-attr reverse setw -g monitor-activity on  # for vim setw -g xterm-keys on  # load average, battery, and date + time set -g status-right "#[fg=magenta] #(cat /proc/loadavg|awk '{print
