One other candidate might be the underscore, though it's a
shifted key which makes it a little more difficult, it is
usually in a pretty predictable place (unlike the
backslash/pipe key which I find all over the keyboard
depending on whose machine I'm using...makes typing DOS
file-paths a pain).
Even the underscore's location may vary.
Ah...good to know. In supporting our office, all of which have
US QWERTY layouts, I have to look for the backslash on each
machine I visit but the underscore is at least predictably "shift
plus the key to the right of zero which contains the minus and
underscore". As for the backslash, on one, it's above a flat
Enter key to the right of the ]/} key. On another it's between
the Backspace and the =/+ key. On another coughfreakcough
keyboard, it's *between* the single-quote and the enter-key (let
me say I curse that keyboard every time I use it). Another
keyboard has it down to the left of the spacebar. Gotta love
standards...reminds me of a certain proposed standard with things
like autoSpaceLikeWord95 footnoteLayoutLikeWW8 where "it's
standard unless I decide to change something for an arbitrary
reason." :)
However, I can't say I ever use the underscore for it's default
purpose (I tried it once and thought "that's not gonna be useful").
