#change prefix from C-b to C-a
unbind C-b 
set -g prefix C-a  

#bind C-a C-a to 'home', or start of line, which was C-a previously
bind C-a send-prefix

#reload tmux.conf message
bind r source-file ~/.tmux.conf \; display "Reloaded ~/.tmux.conf"

#-------------------------------------------------------#

#Create R development environment with multiple windows
#-------------------------------------------------------#
#start off by renaming current window to R, then split, etc

         select-window -t :=1 \;\
         rename-window 'R' \;\
