rofi-i3-bindsym

Displays the bindsyms (with the description, keys and command) in your i3 config and executes on selection.

Config

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.
