I'm trying to change they hotkey for the color picker that's available while the brush tool is selected. When you hold CNTRL you get a color picker, then when CNTRL is released you're back to the brush tool.

Bascially I want to change this hotkey to ALT, but I can't find the command to hotkey. When sorting by hotkeys CNTRL is not listed, though it clearly brings up the brush's color picker when used in the program.

Does anyone know where to find this?

It can be changed in the settings under Canvas Input settings and then Alternate Invocation.

Thank you so much, worked perfectly!
