What can I do with my pen side button?

Squid supports using the pen side button on capable devices. This allows quick access to certain tools and actions. By default, you can hold the pen side button to use the selection tool without having to change the current tool from the tool picker.

In addition, the following gestures are supported. Hold the pen side button and
  • flick left to undo
  • flick right to redo
  • flick up to open the color picker
  • flick down to open the tool picker
The pen side button behavior can be changed in the Squid settings under Input methods, then Primary side button.
