;
; Original version from
; http://www.autohotkey.com/docs/scripts/EasyWindowDrag_(KDE).htm
;
; The shortcuts:
;  Alt + Left Button         : Drag to move a window.
;  Alt + Right Button        : Drag to resize a window.
;  Control + Alt + WheelUp   : Maximize a window
;  Control + Alt + WheelDown : Restore a window
;  Super + WheelDown         : Minimize a window
;  WheelUp                   : Focus window under cursor, then send wheel up
;  WheelDown                 : Focus window under cursor, then send wheel down
;  Super + Middle Button     : Send window to background
;
; You can optionally release Alt after the first
; click rather than holding it down the whole time.

; From Mike Zwagerman, 2009-03-18:
; This changes increase the Maximum Number of Hotkeys allowed
; per interval from the default of 70 to 200
#MaxHotkeysPerInterval 200
