Igloo Annotation is a tool to allow a user to draw on/annotate the Igloo canvas using a controller, such as the Steam controller.

Setup:

Igloo Annotation is turned on and off via the Warper GUI; it can be found under config → controller → annotation:

Igloo Annotation is then controlled using a supported game controller such as a Steam controller, which we'll use for this example:

DPad down - Undo
Dpad up - redo
Dpad left/right - cycle colour of annotations
Back button - Calibrate Gyro
Right trackpad (click this in) - clear all annotations
Right shoulder - Increase cursor size
Left shoulder - decrease cursor size
Right trigger - draw/annotate
Left trigger - erase

Additionally, the a & b buttons, when used in conjunction with other commands, alter the behaviour of the controller, allowing you to control capture inputs

With b held:

Left shoulder - Reduce the size of the highlighted capture window by ten levels
Right shoulder - Increase the size of the highlighted capture window by ten levels
Left trigger - Reduce the size of the highlighted capture window by one level
Right trigger - Increase the size of the highlighted capture window by one level

a allows you to "grab" a capture input, allowing you to move it around the canvas with the Steam Controller's gyroscope.
