tmux_usage

The formatting here is simple enough to understand (I would hope). ^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+, so M-x is left-alt+x

I use Control + a instead of Control + b to be my prefix key in tmux.
.tmux.conf:

unbind C-b                                                                                                              
set -g prefix C-a
unbind %
bind | split-window -h
bind - split-window -v
set -g default-terminal "screen-256color"

# move around panes with hjkl, as one would in vim after pressing ctrl-w
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

# resize panes like vim                                                                                                                                                                                        
# feel free to change the "1" to however many lines you want to resize by, only
# one at a time can be slow
bind < resize-pane -L 1
bind > resize-pane -R 1
bind - resize-pane -D 1
bind + resize-pane -U 1
