My focus was on SCC and not CH+S.
My maximum area was 1000 (default?). Changed to 6000 and it's back working like a charm for images.
Ctrl+C in thumbnail (screenshot panel) copies the file so I can paste in a different location/folder/etc. Got it.
All I'd like now is a hotkey to copy the file path. Till then I'll keep using the right-click copy path name with the mouse.
I knew about the hotkeys tab. I should have worded it differently. I meant how do I get the keystrokes in there. Figured it out.
Put cursor in the line after "None" then start with (press) Ctrl or Alt and the other keys you want to assign to it. "None" is replaced with the keys. Got it.
