Hello Jerry,
This was the problem in the first place.. I did not get any rawKeyDown
message, when I pressed ctrl or shift and yes I'm developing on a mac.
Even tho we're doing mainly software for the Windows users, I would
like to make it OS X/Linux/Unix compatible, since they can make big
difference in the future. I think I can deal with mouseWithin
messages, if I raise the idleTicks to some low rate like 10 seconds in
cases, when it's not needed. Thanks for your help Jerry and the rest,
this was really nice of you.

Sakari,
If you want to change the cursor anytime a modifier key is depressed
on both Windows and Mac, then I believe you will have to use either
a polling method (send in time), idle message or mouseWithin--none
of which are very processor friendly and can interfere with other
things like clicking links.
HOWEVER...if you are developing for Windows only, then you are in
luck. ANYTIME you depress a mod key, the rawKeydown message is sent.
This may also be so for Linux, but I have not tested that.
I would dearly love to have the ability to check mod keys anytime
via rawkeydown message on Mac as well, but, at least in my tests
over the years, this is not yet possible. As anyone who has
developed a standalone application knows, there is an "event loop"
that spawns things like the idle message and mousewithin message
that Rev has. I am baffled why it is so hard to send a message
anytime any key is depressed from within the Revolution engine. How
could the Mac OS forbid such a thing. It never used to when I worked
on apps in C and Pascal on Mac OS 7.
We check mod keys for no-click inspection in GLX2, so I think I
understand the exercise. We need to know mod key states even if the
mouse is not within rect of the stack as well. So we check the mod
key states while the mouse is moving and then send a series of
"staggered" messages every 350 millisecs after the mouse stops
moving to catch modifier key states outside of the stack window,
etc. This taxes our processor time very, very little and provides
almost zero interference with the IDE's other tasks, fortunately.
But it is certainly not ideal as the staggered messages die out
after a few seconds.
Best,

Hello folks,
Was wondering how to change the mouse cursor
behavior, when user
presses either ctrl or shift key? Like in photoshop
with select tool
where u can add to selection by pressing shift and
remove from
selection by pressing ctrl? If anyone has
implemented anything like
this, any help would be appreaciated. Thank you!

Hi Sakari,
Others already suggested trapping the 'mouseWithin'
message, or polling every 100 milliseconds using a
'send in time' construct; here's a different approach:
##
local sKeysDown
on rawKeyDown pKey
if the keysDown is not sKeysDown then RefreshCursor
pass rawKeyDown
end rawKeyDown
on rawKeyUp pKey
if the keysDown is not sKeysDown then RefreshCursor
pass rawKeyUp
end rawKeyUp
on RefreshCursor
put the keysDown into sKeysDown
if the controlKey is down then
set the defaultCursor to hand
else
set the defaultCursor to arrow
end if
end RefreshCursor
##
Hope this helped,
Jan Schenkel.
