Have you looked at the GetKeyState function? I have not used this function
yet,, but I think it will let you check if the Shift key is being held down.
Holding down the Shift key by itself does not trigger any events that I know
of. It seems like the trick here is to create a function to monitor if this
has happened yet! If you know about when to expect this event, you can use
something similar to:
If GetKeyState ("Shift", iDown, iLocked) Then
; I am assuming the Shift needs to be in quotes. I am sure you are more
familiar with this value/variable than I am!
; The iDown and the iLocked parameters are passed by reference.
; This means these values are set by the function and can be used
afterwards.
If iDown Then
; Shift key is down, perform desired action
HandleSectionRefresh ()
EndIf
EndIf
If the key can be pressed at any time, you may need to place this type of
check in a self perpetuating function using the ScheduleFunction capability.
This would be a function that contains the above code to check the state of
the Shift key. and then schedule the function again. I do have examples of
this way of monitoring if you need to go this route.
From the FSDN:
Function: GetKeyState
Description
Returns by reference both the up/down state of the key, and the toggle state
if applicable. NumLock, ScrollLock, and CapsLock have toggle states.
Returns
Type: Int
Description: TRUE if the keystate was successfully returned.
Parameters
Param 1:
Type: String
Description: The name of the key whose state is to be retrieved. A list of
key names is referenced in keycodes.ini.
Include: Required
Param 2:
Type: Int
Description: Set to true if the key is in a down state.
Include: Required
* Returns data by reference
Param 3:
Type: Int
Description: Set to true if the toggle state is on. For example, if CapLock
is in the on state, then this value will be true.
Include: Required
* Returns data by reference
Version
This function is available in the following releases:
PAC Mate 1.10 and later
JAWS 4.51 and later
Magic 10.5 and later
