That's a really good idea. Maybe the L and E are the 2d letters in the titles you were look at. I long pressed on a letter on the right and it brought up a list of more letters, which turns out to be the 2nd letter in the names in the library. A long press on a letter that popped up turned out to be the 3rd letter in the names in the main library. So, long press on S takes you to the S's in the main library with a popup of more letters, a long press on one of them [P, for example] will give moves you to SP, another long press on the popup [O] gives the 3rd letter for a total of SPO. I was looking up SPOTTED PONY, which is pretty far down in the list.
