I was flying through my work-flow and my fingers got tangled up... I hit a key combo somehow and the behavior of applying things to the currently active image in a group selected images changed.
Previously, if I had 5 images selected and wanted to reject just the one that I had focus on (the active photo), hitting X would reject just that one.
Now, it's rejected all selected images.
This is really slowing down my workflow so how do I revert that behavior so that actions such as reject apply to only one photo out of a group of selected photos?
