Config file
Download the original skippy-xd.rc-default config file and copy it to ~/.config/skippy-xd/skippy-xd.rc and edit it to your liking.
Command Line Usage
Once Skippy-XD is installed, you can run it by entering "skippy-xd" at the command line. This will start the program, activate the window picker once, then exit. However, starting the program produces a brief flicker, so its better to keep the application running in the background as a daemon and just activate it when you want to use the window picker.
To run the daemon, use the following command:
skippy-xd --start-daemon
If for whatever reason you need to cleanly stop the running daemon, do this:
skippy-xd --stop-daemon
Once the daemon is running you can use the following command to activate it:
skippy-xd --activate-window-picker
However, sometimes pressing the Return key to run this last command also causes the window to be selected, so it is probably more effective in testing to do this:
sleep 1 && skippy-xd --activate-window-picker
This will wait 1 second, then activate the picker.
