HEAVILY BASED FROM:
ALT-TAB REPLACEMENT (WITH ICONS AND WINDOW TITLES IN A LISTVIEW).
      Latest version can be found at: http://file.autohotkey.net/evl/AltTab/AltTab.ahk
      Forum topic for discussion: http://www.autohotkey.com/forum/viewtopic.php?t=6422
but slightly modified for mac like behavior
	  
HOTKEYS:
  Default:    Cmd+Tab - move forwards in window stack
              Cmd+Shift+Tab - move backwards in window stack
              Cmd+Esc - cancel switching window

EVENTS:
  Double-click a row to select that item and switch to it.

  Type first letter of program's title to cycle through them while still holding Alt

  Columns can be sorted by clicking on their titles.

  Tabs (window groups) can be re-ordered by drag-and-drop.

  Right-Click (context menu):
    Basic hotkey support for switching to specific windows (using window groups and adding window classes)
    Exclude (and un-exclude) specific windows and specific .EXEs - see "Window Groups" below.
    Edge-docking - dock windows to the edges of the screen and have them auto-hide (like the taskbar can).
    Window Groups - define lists of windows to easily switch between only showing certain apps.
    Manage groups of windows and processes (min/max all, close all, etc).

  Close windows:
    Alt+Middle mouse - close window under the mouse pointer in the Alt-Tab listview.
    Alt+\ "hotkey"  - close selected window (while list is displayed)
    Alt+/ "hotkey"  - close ALL windows whose EXE matches that of the selected entry (while list is displayed)
    Process menu entry - end selected process or all instance of the EXE in the list.

SETTINGS:
  See "; USER EDITABLE SETTINGS:" section near top of source code.

TO EXIT:
  Choose Exit from the system tray icon's menu.

NOTE: Stroke-It (and maybe other mouse gesture programs) can cause the context menu to be shown twice/problematic.
        Solution: exclude the program within the gesture recognition program (window title = Alt-Tab Replacement).
)


LATEST_VERSION_CHANGES = ; Gui, 98
(LTrim0

TO DO (maybe):
  settings window
  save other settings between restarts
  include a filter for docked windows to be displayed in alt-tab or not (ie a tab for docked windows) - perhaps alter title? e.g. DOCKED***
  stick items to top or bottom of list
    use listview insert command to place windows at specific locations in list?

LATEST VERSION CHANGES:
since 25-04-06:
  +: Groups of windows are shown in tabs - they can be re-arranged by drag-and-drop.
  +: Settings tab.
  + & FIX: Updates to the listview colour code - much smoother now (thanks to ambi for updating the Listview script).
  + & FIX: Sorting of columns with direction indication ([+] or [-])
  +: Mouse wheel over the TASKBAR scrolls the list - Middle button SELECTS a window in this mode (it normally CLOSES a window!).
  +: Save data on big changes (in addition to program exit) - e.g. new group created, hotkeys changed
  CHANGE: Selections with the mouse are now made with a double click (or just release the Alt key) instead of a single one.
  CHANGE: Adjusted display position to be centered by default.
  CHANGE: Dialog windows only indicated by red higlight (not by title too).
  CHANGE: Not Responding windows indicated in a new column (not by title).
  CHANGE: Many speed optimisations and code improvements (it's almost decipherable now ;-))
  FIX: Handling of "Not Responding" windows with no delays.
