Ctrl+f on WIndows and cmd+f on Mac and type what I'm looking for.  The index and contents tables are good, but obviously can't have everything in them, so I use the find feature a lot.

But I can’t find that instruction in the manual now.  Anyone know where I might have gotten that notion, or did I just make it up?
