Invert Pixel Selection area SHORTCUT not working. + Masked area assist?


Recommended Posts

Hello!

I have read that to invert a pixel selection (selected area) quickly, the shortcut is CMD+i. It is definitely not working for me. Is there maybe somewhere in AP (on Mac) where I can "set" what these shortcuts will do (if that is the reason I'm having this problem)?

 

*In the attached screenshots, I show: 1) an arbitrarily selected area (my face), then 2) when I hit the mask button it (correctly) masks out my face and hides everything else around the selected area. 3) Then I show what happens when I press CMD+i (in my attempt to invert the mask - so to select everything outside the face's area) and the selection ISN'T inverted but something else happens instead...), and 4) I show a successful selection inversion (and masking out of the surroundings, while hiding my face) - which is what I was unsuccessfully trying to do with the CMD+i shortcut before - and achieved this only via the "long way" of pressing the Invert button in the Channels' tab.

 

Also, is there some kind of view assist option which I can toggle on to make it more obvious which area/s is/are selected? Say, by dimming the unselected area/s?

I'm not sure where you read that, but if you look in the Select menu (since you're working with a Selection) you'll find what your actual shortcut is. If you haven't changed them it's probably Cmd+Shift+I.

thanks! But since I can't read German, reading walt.farrell's reply above, it looks like shift+cmd+i will invert the pixel selection (so I guess that's what your 1st photo shows). But your second photo looks like it shows that cmd+i ALSO "inverts". But what does that command invert, then, if not the pixel selection area? The colors?

Yes, as you already saw from your above image posting.

What v_kyr said plus

Select/Invert Pixel Selection changes the selection so that what was selected now isn't and what wasn't is

Layer/Invert basically applies an inverted Curves Adjustment

The Layer content, since it's in the Layer menu. And when you happen to have a pixel selection active, it would act on the selected pixels of the selected layer.
