Repeating key combination issue

[shawn9]

I created a mapping like this:

Code: Select all

!j::Send {Down}

And when I press alt+j at the first time, it works well. But when I keep pressing these key combination without release, it sends j only.
I tried the following methods but failed:
1.

Code: Select all

*j::
If GetKeyState("alt") {
  Loop
  {
     Send {DOWN}
     sleep 500
     If !GetKeyState("j") {
       Break
     }
  }
}
Return

2.

Code: Select all

*j::
If GetKeyState("Control")
 Send {DOWN}
Else
 Send {Blind}x
Return

Any suggestion is welcome.
Thanks!

Worked here. Test in Notepad, with no other code in the script, and no other scripts running.

Thanks for your confirmation.
I tested in Notepad on other three Windows10 laptops. And found different behavior on different laptop.
The version of AHK is 1.1.34.02.
The whole script is as follows:

!j::Send {Down}
!k::Send {Up}
!h::Send {Left}
!l::Send {Right}

The test scenario is:
Firstly, I input 100 lines with repeated content: 'aaaaaaaaaaaaaa' in Notepad.
Then I use alt+j/k/h/l to navigate, I will see letter j/k/h/l between letter a.
The point is the probability of occurrence is different, e.g. the one laptop is about 60%,
the other is about 5% more or less.
What is the cause of probability changing?
Is there any other stable solution for it? I means making probability zero.

By the way, I refered this links, but failed:

Have you tried using a fixed priority setting? https://www.autohotkey.com/docs/commands/Process.htm#Priority

Thanks for your quick response!
I just tried to increase script priorty as follows:

Code: Select all

Process, priority, , High ; Make script own priorty high
!j::Send {Down}
return
!k::Send {Up}
return
!h::Send {Left}
return
!l::Send {Right}
return

But make no difference. The problem still exists.

Perhaps:

Code: Select all

!j::SendInput {Down}
!k::SendInput {Up}
!h::SendInput {Left}
!l::SendInput {Right}

I made difference. After use SendInput instead of Send, the probability of unexpected behavior occurrence becomes lower(almost less than 3%)
And I think it is acceptable, although it is not perfect

Thanks guys for your help!
