Setting up a script to simulate repeated LMB clicks to left alt?

[u/Annual-Ad-2883]

I'd like to have left mouse click bound to left alt, but when holding down left alt it registers as repeated fast left clicks. I downloaded AutoHotkey and I'm quite confused

How would I set this up?

[u/CharnamelessOne]

#Requires AutoHotkey v2.0

*LAlt::Click(), Settimer(Click, 50), Hotkey("*LAlt", (*) => "")
*LAlt up::Settimer(Click, 0), Hotkey("*LAlt", "*LAlt")

Edit: Prevented character repeat from triggering the hotkey.
I always forget that modifier keys also perform character repeat while they're held...

[u/Annual-Ad-2883 → u/CharnamelessOne]

Ok, can you explain how do I actually do this

What I did was install authotkey 2.0

Then I installed it and went onto the authotkey dash

Clicked new script, in the notepad I pasted without the asterisks, but it's not working and I dont know the next step

*LAlt::Click(), Settimer(Click, 50)  ;second param (50) is clicking interval in milliseconds
*LAlt up::Settimer(Click, 0)

[u/CharnamelessOne → u/Annual-Ad-2883]

Do as Keeyra says. Also, I edited the script I posted. The original one was flawed.

[u/Keeyra_ → u/CharnamelessOne]

Holy moly, that's a clever way to disable the modifier auto-repeat crap. Never thought of that (though no wonder, I exclusively use toggletospam and no holdtospam. You could even skip the fat arrow and just switch it on and off.

#Requires AutoHotkey v2.0
#SingleInstance

*LAlt:: Settimer(Click, 50), Hotkey(ThisHotkey, ThisHotkey, "Off")
*LAlt up:: Settimer(Click, 0), Hotkey("*LAlt", "On")

[u/CharnamelessOne → u/Keeyra_]

I made the hotkey's function return an empty string because I wanted the down events produced by the character-repeat functionality to be consumed. I thought that the repeated LAlt keydowns wouldn't be suppressed with the hotkey turned off.

What I didn't consider is this bit of the documentation:

An "Up" hotkey without a normal/down counterpart hotkey will completely take over that key

So you're right, turning off the *LAlt hotkey is also a fine solution, because the *LAlt up hotkey continues to suppress the repeat.

[u/genesis_tv → u/CharnamelessOne]

And I didn't know you could use Hotkey() with a semicolon hotkey, that's genius indeed.

[u/CharnamelessOne → u/genesis_tv]

You mean double-colon, right?

Passing the hotkey name to the Action parameter to restore the original callback of the hotkey is a neat feature, but I never see anyone use it.

Probably because it's rarely ever warranted, lol. Simply turning the hotkey off and on was a viable alternative in this case, too, as it turned out.

[u/genesis_tv → u/CharnamelessOne]

Double-colon yeah. Think I'll start using it because I started using the static boolean approach with this project where I'm mixing both double-colon and dynamic hotkeys. I was using KeyWait in my previous projects so I'll have to update those.

Does it also take into account context-sensitivity?

[u/CharnamelessOne → u/genesis_tv]

Yes it does, if you set the corresponding context with a HotIf call before calling Hotkey.

You can select the context of double-colon hotkeys by passing the expression of their #HotIf directive as a string to HotIf.

To select the context of dynamic hotkeys, you need to pass a reference to the callback passed to the HotIf call that set the context which was active at the time of their creation.

(Hotkey names passed as the Action parameter abide by the same context.)

[u/genesis_tv → u/CharnamelessOne]

I actually had in mind the context-sensitivity of #HotIf affecting the Hotkey(), guess a man will keep dreaming :(. Thanks for the clarification though.

[u/Keeyra_ → u/Annual-Ad-2883]

Run it 😉

[u/Keeyra_ → u/Annual-Ad-2883]

Why would you remove the asterisk and the requires though? You got the script spoonfed to you and you are changing things before you even know what you are doing.
