Where is the "Invert" command?

[Roger Breton]

Working with Layer Masks, I often select the Mask to "Invert" it, using the usual Ctrl + I keyboard shortcut BUT I never knew where that command "hides"? In which menu to find it? Bugs the hell out of me...

In Photoshop it's Image>Adjustments>Invert

Thank you!! Under the French UI, it is "Négatif".
No wonder I could not find it 🙂
I owe you one...
