Using keyPressed() method on Canvas

Question

I have a List screen with certain items and I want to detect when the users presses a numeric key from the keypad while on that list, in order to call a function. Im using NetBeans 5.5 and Ihave no Canvas class anywhere on the app... I'd like to get some directions on how to implement it in this case.
Thanks in advance!

I tried your game on IE and experienced the problem. It did not happen for me on Firefox.
I see you have a repeat loop with an updateStage. This is not the best approach. As in another thread, the advice is to avoid this and rather loop within a frame. Say we created a property variable called pKeyPressed, where 1 is when they are pressed, 0 when it is not, you could toggle this property and then loop in the frame when the property is 1.
For example:
property pKeyPressed
property tempoDelay, locOld, sptObjm xy
on beginSprite me
  pKeyPressed = 0
end
on moveObj me,xy,nomeSptBase
-- do whatever
if (locOld <> sprite(sptObj).loc) AND (_key.keyPressed(123) or _key.keyPressed(124) or _key.keyPressed(125) or _key.keyPressed(126)) AND not ePorta then
pKeyPressed = 1
else
  pKeyPressed = 0
-- do other stuff (which would follow after your previous repeat loop
end if
end
on exitFrame me
if pKeyPressed = 1 then
if the timer > tempoDelay then 
  startTimer
  locOld = sprite(sptObj).loc
  sprite(sptObj).loc = (locOld + xy)
end if
member("Debug").text = member("Debug").text & ENTER & _key.keyCode
end
I changed:
the loc of sprite sptObj
to
sprite(sptObj).loc
Is there any reason you're using ENTER instead of RETURN?
