AutoIt Hotkeyset function _autoit

Hotkeyset ("Hotkey" [, "function name"])

Parameters

Hotkey	The hotkey to be set is the same as the key format used by the Send () function.
The name of the function	[Optional parameters] The name of the function to invoke when the hotkey is pressed. Leave blank to undo the previously set hotkey.

return value

Success:	The return value is 1.
Failed:	The return value is 0.

Attention

Each script program can register up to 64 hot keys at the same time.

If two autoit scripts have the same hotkey set, you should avoid running both scripts (otherwise the second script will not be able to capture the hotkey unless the first script terminates running or the conflicting hotkey is revoked before the second script sets the hotkey).

After the user presses the hot key, * usually * interrupts the current running AutoIt function/statement and runs the user function associated with the hotkey until it completes or is interrupted. There are, of course, some exceptions:
1 if the current (running) function is a "blocking" (blocking) function, the keystroke action is buffered and waits for the blocking function to complete the operation before continuing. MsgBox and Fileselectfolder are typical blocking functions. You can try the hotkey shift-alt-d defined in the following sample script.
2 If you select the pause script on the AutoIt tray menu, any hotkey pressed during the pause will be ignored.

Unable to set hotkey:

Ctrl+alt+delete	Reserved by Windows
F12	is also reserved by Windows, involving APIs.
Enter (enter) key on keypad	Use {Enter} to capture the return key on both the main keyboard and the keypad
Win+b,d,e,f,l,m,r,u; and Win+shift+m	These are the shortcuts that are built into Windows. Note: Win+b and win+l are reserved only by Windows XP systems above.
Alt, Ctrl, Shift, Win	These are the auxiliary buttons!
Other	Any global hotkey defined by a third party software, any hotkey consisting of two or more "base keys" (such as ' {F1}{F2} '), any type such as ' {Lalt} ' or ' {Altdown} '.

When a hotkey is set, AutoIt attempts to capture the specified key event but does not pass it to the activation program, but there is one exception: pressing the Lock key (including NumLock, CapsLock, and ScrollLock) will toggle its state at all times! If you want to send the captured hotkey event to the activation program, you must first log off the hotkey and then call SendOr ControlsendFunction:

; Capturing and passing key events
Hotkeyset ("{ESC}", "Captureesc")
Func Captureesc ()
; ... Here you can define the various tasks to be done
Hotkeyset ("{ESC}")
Send ("{ESC}")
Hotkeyset ("{ESC}", "Captureesc")
Endfunc
