bind-key -n M-l select-pane -R

# open the '~/.tmux.conf' and comment out this line:
set -g prefix2 C-a
# start with mouse mode enabled
set -g mouse on
# Release Ctrl+a
unbind C-a

# Don't forget to go to tmux dir and add this change into `.tmux.conf`
# Disable Ctrl-a by Bahram
# set -g prefix2 C-a                        # GNU-Screen compatible prefix
# bind C-a send-prefix -2
