如何在 Autohotkey 中分配按 Alt 键两次（Alt+Release+Alt）的热键？

Question

如何在Autohotkey中分配快速按{Alt}键两次的热键？

换句话说：如何将Press Alt+Release Alt+Press Alt指定为热键？
换句话说：如何分配 key down {Alt} key then key up {Alt} key then 快速 key down {Alt}?.

我想设置释放{Alt} 键然后再次按下它（非常小）以激活热键之间的时间。
• 示例： 如果用户按下{Alt} 键然后释放它然后等待5 秒然后再次按下{Alt} 键，热键根本不应该工作或激活。但是如果他在 1.5 秒之前再次按下{Alt} 键，那么热键将起作用。我希望能够设置这个时间。
• 类比： 这类似于双击鼠标按钮并设置第一次和第二次单击之间的时间，以便双击操作触发。但我正在寻找的是为键盘键设置双击。

Answer 1

Autohotkey 论坛上有一个脚本已经完成了这个任务：RapidHotkey。

页面上列出了两个必须包含在脚本中的函数，但它们使您能够设置热键、所需的点击次数以及两次点击之间允许的时间。这方面的一个样本可以是

~Alt::RapidHotkey("myLabel", 2, 0.3, 1)

myLabel:
Msgbox Alt was double clicked
Return

Answer 2

如果你想在 Autohotkey 中，在按下热键两次（或点击次数）时执行 AHK 操作

例如单击 (ALt 2x) - 执行操作。

您可以使用这两个 AHK Scipt。 （第一个脚本很大，但你可以做很多想法。）

1 - KeypressValueToREG.ahk - 这会将任何（键盘点击动作）和（鼠标点击动作）只放入一个（Windows 注册表项）

2 - ShowKeypressValue.ahk - 这将直观地显示 KeypressValue 并且如果按两次 Alt 键，它将运行 Ahk 代码。

注意：您需要同时运行两个脚本。

KeypressValueToREG.ahk

;KeypressValueToREG.ahk comes from KeypressOSD.ahk that was Created by Author RaptorX
; Open this Script in Wordpad and For Changelog look to the Bottom of the script. 
;This code works with a getkeyname from a Dllcall (See Bottom Script- by Lexikos)

如果您想使用精确的 MilliSeconds 控制值。

你只能！使用这个例子：

example2.ahk

注意：在 Line (SetTimer, CountClicks, 100) 中，您可以优化（更改）数字 100。（以便它在您的系统上正常工作。）（在后台运行的任何 Ahk 脚本的默认值 = 250ms )

#NoEnv
#SingleInstance force
;#NoTrayIcon

a1 := -1
b1 := 0

esc::exitapp ;click (esc) key to stop the script. 

;~ key the default function Alt is also active. 
;and if you Click the Alt Button 3x times, it will Execute Ahk Code Part 3
~Alt::
if(a1 = -1)
{
a1 := 4
#Persistent

}
else
{
a1 := 3
}
return

CountClicks:
if(a1 = 3)
{
b1 := b1 + 1
}
if(a1 = 0)
{

Answer 3

使用这个简单的脚本：

LAlt::
    If (A_PriorHotKey = "LAlt") AND (A_TimeSincePriorHotkey < 200){
        Send, {LAlt Down}
        KeyWait, LAlt
        Send, {LAlt Up}
    }
return

if 语句会检查LAlt 热键是否在最后的200 毫秒内被使用过，如果是，它将保持LAlt 键向下，当LAlt 物理上升时（你松开键)，它将在操作系统中反映相同。 否则，它将什么也不做，例如，如果序列是LAlt，某个其他键然后再次LAlt，它不会激活，或者如果按下LAlt 之间的时间不够快（超过@ 987654329@ms) 它也不会激活。

Answer 4

这可以检测两次快速 ALT 按下：

~LAlt::
    If (A_PriorHotKey = "~LAlt") AND (A_TimeSincePriorHotkey < 200){
        SoundBeep, 750, 500
    }
return

它基于Shayan's answer，但我添加了~ 以使其工作。没有它，ALT+TAB 和其他 ALT+xxx 不起作用。
