I was working on a photo horse portrait in which I wanted to dehaze only the background. Using the brush tool, with auto mask checked, I painted in the dehaze. I then wanted to make some further adjustments to only the foreground, so while still with the background selected, I chose Invert Selection form the Edit menu. Rather than inverting the selection, LR jumped to the previous image in the Library module instead of inverting the selection. Anybody have a similar experience like this?
A very late reply: The Edit > Invert Selection does something completely different from what you expected. It selects all the unselected photos in the curremt folder or collection and deselects all the currently selected photos.
It isn't possible to invert the masks of local adjustments, except for radial filters. Many people have requested this over the years:
