More Example of config.yml

The following wiki pages can be edited by everyone.

If you have a nice configuration, please share ~/.config/fusuma/config.yml with everyone.

Threshold and Interval

if command: properties are blank, the swipe/pinch doesn't execute command.

threshold: is sensitivity to swipe/pinch. Default value is 1. If the swipe's threshold is 0.5, shorten swipe-length by half.

interval: is delay between swipes/pinches. Default value is 1. If the swipe's interval is 0.5, shorten swipe-interval by half to recognize a next swipe.

command: property for assigning commands

On fusuma version 0.4 command: property is available! You can assign any command each gestures.

shortcut: property is deprecated, it was removed on fusuma version 1.0. You need to replace to command: property.

swipe:
  3:
    left:
-      shortcut: 'alt+Left'
+      command: 'xdotool key alt+Left'
    right:
-      shortcut: 'alt+Right'
