Displays the bindsyms (with the description, keys and command) in your i3 config and executes on selection.
Put this in your i3 config and adjust the location of the script.
# i3wm bindsyms
bindsym $mod+Shift+space exec --no-startup-id rofi -modi rofi-i3-bindsym:~/git/rofi-i3-bindsym/rofi-i3-bindsym.py -show rofi-i3-bindsym
if your i3 config is not in ~/.i3/config you'll need to change this line:
filename = os.path.expanduser('~') + '/.i3/config' #? Change this if you have your config file located somewhere else.If you like to see bindsyms without a decription remove line 29.
