Where in the docs for the IFF keyboard shortcut?

GROUPS:

When I'm thinking about math, and I need to type the if-and-only-if symbol, but esc-iff-esc doesn't work, and then I search the docs for 15 minutes, then Google, but still can't find the right key-sequence to type (what was I working on before this? can't remember offhand), where exactly in the docs should I be looking for information I need about which keys to press, please?

Joe,

All those symbols (and more) are found here - Mathematical and Other Notation. Then under "Operators" is the link for "Logical and Other Connectives" and you will find multiple versions of what you want such as [Congruent] (esc===esc) or [DoubleLeftRightArrow] which can be typed as esc<=>esc or the long version esc<==>esc.

I hope this helps.

Regards,

Neil

Thanks very much. I have never seen that page before, despite having been using Mathematica for 15 months.

Joe,

I found that page by starting in the Documentation Center and typed "esc" figuring that most of the special characters use esc. The first link that came up was "Special Characters: Mathematical and Other Notation". This was an overview of many characters but it referenced the complete tutorial at the bottom.

Often I find the best information by starting with a related topic (as close as I can get) and scrolling to the bottom of the documentation page and clicking on the related tutorials, guides, and links -- the pages are usually well linked. I also think the related commands are usually well done.

Regards,

Neil

Thank you. The local version of the Document Center (not the internet version) does not give that result when I try "esc" (not that I was clever enough to try "esc" until you mentioned it)---at least not on the first page of results. I did end up finding a pathway to that information from the start-page after your 1st post, which is important so I can find my way back there when I forget the shortcut again.

That's odd. I am using a Mac. Is it different on a PC?

This is my search: Its the first result from the documentation.

Windows 10, Mathematica 11.1.0.0 here.

970 results compared with the 980 indicated in yours. "Entering Greek Letters (Tutorial)" is the top answer here.
