A thank you to those who posted tips, although I do wonder how we are expected to know this! How did you all find out?

I do find these things go out of their way to /not/ offer what Buxton called a "self-revealing interface"; most of the apps I use don't even have a basic help page or even a legend for special symbols on their display!

Maybe it really /is/ a generational thing. I recall being similarly amazed when my gradeschool son demonstrated (matter of factly) the 'hidden' chambers full of coin in Commander Keen, like jumping in a tunnel because, you never know, the ceiling might be an illusion, and kids think the character's cringe and bleep of hitting a hard ceiling is funny. They were priming my kids...

I don't recall where I learned it, but I just downloaded and checked: It's in the Tips app that comes installed by default on every iPhone. But it's probably like a lot of other things I've learned about computers over the decades, I probably just tried something to see what would happen. It was that, or I read it in the short features guide they include with every phone before tossing it into the bin.
