@McCannon — Yep. I generally do File —>New Tab. Laziness on my part b/c I don't like to memorize a lot of keyboard 'short cuts'. I know that I'm probably in the minority but I figure there's only so much RAM left in my brain.
But I did try "Command" T just now and bingo! It worked.
"Control" T did not work.
Mostly when people give out computer tips I always like to point out that some apply only to Macs and some apply only to PCs and some depend on which browser is being used. That's all. By now, I would hope a lot of the shortcuts would be the same across most systems. Years ago they weren't and that was just silly.
