CODE:

~LButton::MouseSpeedToggleHold(3) ; change the speed here

MouseSpeedToggleHold(newSpeed) {
    static GetMouseSpeed := 0x70
    static SetMouseSpeed := 0x71
    DllCall("SystemParametersInfo", "UInt", GetMouseSpeed, "UInt", 0, "UIntP", &originalSpeed:=0, "UInt", 0) ; Get the original speed
    DllCall("SystemParametersInfo", "UInt", SetMouseSpeed, "UInt", 0, "UInt", newSpeed, "UInt", 0)           ; set the new speed
    KeyWait RegExReplace(A_ThisHotkey, "^.*?(\w+)$", "$1")                                                   ; wait for this hotkey
    DllCall("SystemParametersInfo", "UInt", SetMouseSpeed, "UInt", 0, "UInt", originalSpeed, "UInt", 0)      ; restore the speed
}
