Hi Beat,
Usually, I provide help through the command-? shortcut and sometimes I
add the help key as an alternative. The help key only exists on
extended keyboard and not on the MacBook for example. I don't see a
help key on my (old) Windows keyboard.
The excape key would be a very bad replacement for the help key. Far
from intuitive. I'd go with control-? on Linux and Windows and
command-? on Mac.
You need to test whether this works. On my keyboard, the question mark
key is the same as shift-slash. So, often I do this:
switch theKey
case "/"
case "?"
go to stack "Help"
break
end switch
Best,
Mark

Is the 'help' key (on mac keyboards) a good idea?
I am looking for a good key to invoke a special help function. If
the user presses this key, then visual feedback by means of an image
of a question mark will be displayed if the cursor is within an
object that has this special help function. By clicking, the user
will be taken to that special help part.
I have considered the 'h' key, but it interferes with fields,
meaning if the focus is on a field, it will write 'hhhhhhhhh' to the
field.
Function keys leave also a trace in a field (the square for
unprintable chars). The control or command keys are being used for
other things.
The 'help' key (keyNr 268762986) can be trapped and does not do
anything in a field, so it looks promising. I noticed that in other
apps, if pressed, it shows a question mark, but not in my stack. (I
can code for the question mark and all other stuff I need).
I guess my question is : Does this key also exist on all Windows
keyboards (or is there an equivalent) AND can I safely use the
'help' key in my app, so it does not interfere with anything that is
there anyway. And will this work on all systems (I am on Mac), like
XP, Vista, Windows 7 etc.
If the 'help' key is not universal, would the Escape key be a
solution? Or any other suggestions?
Thanks a lot,
Beat
