POST KEY


POST KEY ( code {; modifiers {; process}} )

Parameter	Type	Description
code	Longint	Character code or function key code
modifiers	Longint	State of modifier keys
process	Longint	Destination process reference number, or Application event queue, if omitted, or 0

Description

The POST KEY command simulates a keystroke. Its effect is as if the user actually entered a character on the keyboard.

You pass the code of the character in code.

If you pass the modifiers parameter, you pass one or a combination of the Events (Modifiers) constants:

Constant	Type	Value	Comment
Activate window bit	Longint	0
Activate window mask	Longint	1
Caps lock key bit	Longint	10	Windows and OS X
Caps lock key mask	Longint	1024	Windows and OS X
Command key bit	Longint	8	Ctrl key under Windows, Command key under OS X
Command key mask	Longint	256	Ctrl key under Windows, Command key under OS X
Control key bit	Longint	12	Ctrl key under OS X, or right click under Windows and OS X
Control key mask	Longint	4096	Ctrl key under OS X, or right click under Windows and OS X
Mouse button bit	Longint	7
Mouse button mask	Longint	128
Option key bit	Longint	11	Alt key (also called Option under OS X)
Option key mask	Longint	2048	Alt key (also called Option under OS X)
Right control key bit	Longint	15
Right control key mask	Longint	32768
Right option key bit	Longint	14
Right option key mask	Longint	16384
Right shift key bit	Longint	13
Right shift key mask	Longint	8192
Shift key bit	Longint	9	Windows and OS X
Shift key mask	Longint	512	Windows and OS X

For example, to simulate the Shift key, pass Shift key mask. If you do not pass modifiers, no modifiers are simulated.

If you specify the process parameter, the keystroke is sent to the process whose process number you pass in process. If you pass 0 (zero) or if you omit the parameter, the keystroke is sent at the application level, and the 4D scheduler will dispatch it to the appropriate process.

Example

See example for the Process number command.
