[AHK]只在某些特定情景生效的热键

;在某特定控件激活时生效。可以在记事本中测试（编辑窗口为Edit1控件），在Word中不生效：

#If ActiveControlIs("Edit1")
6::Send {F5}
7::MsgBox
#If

ActiveControlIs(Control) {
    ControlGetFocus, FocusedControl, A
    return (FocusedControl=Control)
}

在某类控件激活时生效，代码如下

; 示例 : 在所有的编辑控件中的轻松删除单词的快捷键.
#If ActiveControlIsOfClass("Edit")
^BS::Send ^+{Left}{Del}
^Del::Send ^+{Right}{Del}

ActiveControlIsOfClass(Class) {
    ControlGetFocus, FocusedControl, A
    ControlGet, FocusedControlHwnd, Hwnd,, %FocusedControl%, A
    WinGetClass, FocusedControlClass, ahk_id %FocusedControlHwnd%
    return (FocusedControlClass=Class)
}

#If

无需激活在某类窗口上即生效。代码如下

; 示例 : 在任务栏上滚动鼠标来调节音量.
#If MouseIsOver("ahk_class Shell_TrayWnd")
WheelUp::Send {Volume_Up}
WheelDown::Send {Volume_Down}

MouseIsOver(WinTitle) {
    MouseGetPos,,, Win
    return WinExist(WinTitle . " ahk_id " . Win)
}

在某特定窗口激活时生效，用#IfWin 指令可以简单地创建窗口激活时的、上下文相关的热键. 例如:

#IfWinActive ahk_class Notepad
#space::MsgBox You pressed Win+Spacebar in Notepad.

#IfWinExist ahk_class Notepad
#n::WinActivate  ; 激活由 #IfWin 找到的窗口.

在某些窗口激活时生效，通过 #IfWinActive ahk_group MyGroup 使用窗口组
