At home, I use Emacs on a large monitor, and I often switch between it and the browser. Sometimes, when I come back to Emacs, I lose between 1 and 5 seconds finding where current point (the cursor) is. Here's a screenshot of what happens (can you guess where point is?):
Is there a macro that I could launch with a key combination, that would show me very visibly and instantaneously where point is? I imagine like a big red circle appearing for half of a second over the point, or something like that.
