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：如何分配键按下{Alt}键然后按下{Alt}键然后快速按下{Alt} ？。

我想设置释放之间的时间{Alt}键，然后再按一次（非常小），以激活热键。
• 示例：如果用户按下{Alt}键然后松开它然后等待5 秒然后再次按下{Alt}键，则热键根本不应该起作用或处于活动状态。 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：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触发双击操作。 但我正在寻找的是为键盘键设置双击。

Answer 1

Autohotkey 论坛上有一个已经完成此操作的脚本： 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、所需的点击次数和点击之间允许的时间。 这方面的一个样本可能是

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

myLabel:
Msgbox Alt was double clicked
Return

Answer 2

如果您想在 Autohotkey 中，如果按两次热键（或点击次数）执行 AHK 操作

例如 Click (ALt 2x) - 做一个动作。

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（键盘点击运动）和（鼠标点击运动）都设置为一个（Windows 注册表项）

2 - ShowKeypressValue.ahk - 这将直观地显示 KeypressValue，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)

如果您想将它与精确的 MilliSeconds 控制值一起使用。

你只能那么！ 使用这个例子：

例子2.ahk

注意：在行 (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 脚本确实具有默认值 = 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
SetTimer, CountClicks, 100
}
else
{
a1 := 3
}
return

CountClicks:
if(a1 = 3)
{
b1 := b1 + 1
}
if(a1 = 0)
{
msgbox you did Click <Alt> Key > %b1%x times
if (b1=1) 
{
;if Click 1x - Then Execute Ahk Code Part 1 
;Here you can put any code for Part 1

} 
if (b1=2)

;if Click 2x - Then Execute Ahk Code Part 2

} 
if (b1=3) 
{
;if Click 3x - Then Execute Ahk Code Part 3 
;Here you can put any code for Part 3

} 
if (b1=4) 
{
;if Click 4x - Then Execute Ahk Code Part 4

} 
b1 := 0
SetTimer, CountClicks , off
reload ; restart script
}
a1 := a1 - 1
return

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 语句将检查LAlt热键是否在过去200毫秒内被使用，如果是，它将按住LAlt键，当LAlt物理上升（您释放键）时，它将在操作系统中反映相同的情况。 否则，它将什么都不做，例如，如果序列是LAlt ，其他一些键，然后又是LAlt ，它不会激活，或者如果按下LAlt的时间间隔不够快（超过200毫秒），它也不会积极的。

Answer 4

这适用于检测两个快速ALT按下：

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

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