;                    Assign Labels to Button Hold & Double Click
;=======================================================================================
/*
- Allows to use subroutines for Holding and Double Clicking a Mouse Button.
- Keeps One-Click and Drag functions.
- Works with combinations, i.e. LButton & RButton.

Usage:
Assign the function to the Mouse Hotkey and input the Labels to
trigger with GoSub and wait times in the parameters:

MouseExtras("HoldSub", "HoldTime", "DoubleSub", "DClickTime", "Button")
  HoldSub: Button Hold Label.
  HoldTime: Wait Time to Hold Button (miliseconds - optional).
  DoubleSub: Double Click Label.
  DClickTime: Wait Time for Double Click (seconds - optional).
  Button: Choose a different Button (optional - may be useful for combinations).

- If you don't want to use a certain function put "" in the label.
- I recommend using the "*" prefix to allow them to work with modifiers.
- Note: Althought it's designed for MouseButtons it will work with Keyboard as well.
