无法使用AutoHotkey按住键

Question

I have a simple script that doesn't seem to behave as expected:

^j::
  Send, {Down down}
  Sleep, 10000
  Send, {Down up}
Return

I would like it to hold the down arrow key for 10 seconds, and then release. Instead, it presses the down key once, and breaks the script until reload. What am I doing wrong?

Answer 1

Send documentation says:

When a key is held down via the method above, it does not begin auto-repeating like it would if you were physically holding it down (this is because auto-repeat is a driver/hardware feature).

Use SetKeyDelay and specify the number of repetitions:

SetKeyDelay, 30
Send {Down 333}

333 is approximately 10000/30

Alternatively you can do it in a loop and check for other keys in order to stop sending Down key.

Answer 2

Found a nice workaround, try some script like this (adjust the Mynumber variable to your liking and the Sleep aswell)

a::
Mynumber = 10
While Mynumber > 0
{
Send {Down DOWN}
Sleep 10
Send {Down UP}
Mynumber--
}

Answer 3

According to documentation this should work:

To hold down or release a key: Enclose in braces the name of the key followed by the word Down or Up. For example:

Send {b down}{b up}
Send {TAB down}{TAB up}
Send {Up down}  ; Press down the up-arrow key.
Sleep 1000  ; Keep it down for one second.
Send {Up up}  ; Release the up-arrow key.
