Shortcut Opacity

[Prospektor]

Hey everyone, I've been trying to find out if there is a keyboard shortcut to lessen or strengthen opacity, much the way the [ ] buttons do brush size. I want to see if I can map it to my wacom tablet.

any help would be greatly appreciated!!

You can set the layer opacity by pressing the number keys. You can also set the opacity for the brush tool by pressing the number keys.

Layers are 1-0 ( 0 = 100%) . For Brushes I think its shift+1-0 , could be wrong.
