How to invert masks?

[Isaiah]

I was wondering if there is a way to invert a mask in affinity photo... I was working in ps and all u have to do is press command + I to invert the mask... the same shortcut does not work in photo. I’ve just been painting black over the whole layer to work around this but it would be quite a bit more convenient to be able to invert it.

Thanks

Cmd+I works for me... You need to have the mask layer selected in the layer list:
 

 

You'll see black and white swap over in the layer icon.
