下面的ahk脚本提供了windows下alt dragging的能力：

; Easy Window Dragging -- KDE style (requires XP/2k/NT) -- by Jonny
; http://www.autohotkey.com
; This script makes it much easier to move or resize a window: 1) Hold down
; the ALT key and LEFT-click anywhere inside a window to drag it to a new
; location; 2) Hold down ALT and RIGHT-click-drag anywhere inside a window
; to easily resize it; 3) Press ALT twice, but before releasing it the second
; time, left-click to minimize the window under the mouse cursor, right-click
; to maximize it, or middle-click to close it.

; This script was inspired by and built on many like it
; in the forum. Thanks go out to ck, thinkstorm, Chris,
; and aurelian for a job well done.

; Change history:
; November 07, 2006: Optimized resizing code in !RButton, courtesy of bluedawn.
; February 05, 2006: Fixed double-alt (the ~Alt hotkey) to work with latest versions of AHK.

; The Double-Alt modifier is activated by pressing
; Alt twice, much like a double-click. Hold the second
; press down until you click.
;
; The shortcuts:
; Alt + Left Button : Drag to move a window.
; Alt + Right Button : Drag to resize a window.
; Double-Alt + Left Button : Minimize a window.
; Double-Alt + Right Button : Maximize/Restore a window.
; Double-Alt + Middle Button : Close a window.
;
; You can optionally release Alt after the first
; click rather than holding it down the whole time.

; This is the setting that runs smoothest on my
; system. Depending on your video card and cpu
; power, you may want to raise or lower this value.

我最终修改并使用的：

增加了中间键resize的功能,使用LControl替代Alt键：
