Sometimes I'm working on a photo and would just like to see it now full-screen.
I've tried the slideshow, but it takes about 4 seconds for photo to appear - that's too long.
So instead, I do this:
- To Present: Shift-Tab, 'T', 'L', 'L', then move the cursor out of the way.
- To Un-present: 'L', 'T', Shift-Tab, and move the cursor back.
Its more convoluted than I'd like, and I could do without the thin white frame around it surrounded by the thick black frame. A single keystroke to 'present' - full-screen / no borders (my monitors themselves have sufficient borders), and kill the cursor, then another to return to editing would be perfect.
PS - If Lightroom had full-screen editing for multi-monitor mode, this would be unnecessary, but in case Lr4 doesn't have that enhancement, this would be a worthy compromise.
UPDATE: I just automated the keystroke sequences using auto-hotkey, which helps a lot, but still...
