I was near the top of a window displaying CA, and I must have accidentally hit some button, and the result is that my screen now displays everything about 1/3 larger than just before.

I've checked my display settings under System Preferences (I have an iMac), and they are normal; moreover other screens are still sized correctly.

Can anyone tell me what I did?

try hitting "command -" see if that helps

Or maybe hold the control button down and scroll your mouse to change the size.

This. :-)

You can also hit Ctrl and the plus key to zoom in. Ctrl and the minus key to zoom out.

You BROKE it, Mike! Good Lord, I can't have anything nice without somebody screwing it up. Be more careful next time!

I learned something today, thanks!

control + or - won't work on an iMac, its command (or ⌘) + or -

Command - did it; thanks a lot.

And Poet, I can well understand it when the efforts of a superior being are thwarted by the underlings. My most profound apologies!

No problem :-)

Ain't no thing, brother, as long as you don't make a habit of it. :-)

I was wondering about that.
