I have an app with my own view. I handle all the keyboard input on

fine. But when I press insert, I get a question mark cursor and
nothing in
my application.
There is no "insert" key on the Mac keyboard. That key is labeled
"Help" on a Mac keyboard. I'm not sure it'd be a good idea to re-
label the help key as insert as that'll only help those few people
who bought a Mac mini and attached a PC keyboard to it.
This key, on older Mac keyboards, had 'ins' written in a smaller
italicized font above the word 'help', similar to the way the options
keys say 'alt' at the top. On those keyboards you would press the
option key as well as a key that had a second name on it to use it for
it's secondary purpose. There also were a few other keys that had two
meanings on the older Mac keyboards as well, the clear key's secondary
purpose was 'num lock' and the F13, F14, and F15 keys had secondary
meaning on them as well.
I don't however know as if anyone using a newer Mac keyboard would
figure that they could press option help to get the functionality of
the 'insert' key, which I don't think ever did much on the Mac.

A) What does this cursor mean? I see that in some applications it
does that
(turns into a ? and does seemingly nothing), and in others it
brings up
help.
I vaguely remember that it's a special help mode that lets you click
on objects to bring up additional help, but I haven't yet found an
app that actually does anything in response to these "help clicks".
I think most apps that show help are probably Carbon apps. Showing
Apple Guide content (and later Apple HTML Help) was the default
behaviour for the Help key on OS 9.
