Command List

Collapses the specified window into a button on the task bar.

WinMinimize [, WinTitle, WinText, ExcludeTitle, ExcludeText]

Parameters

WinTitle The title or partial title of the target window (the matching behavior is determined by SetTitleMatchMode). If this and the next 3 parameters are omitted, the Last Found Window will be used. If this is the letter A and the next 3 parameters are omitted, the active window will be used. To use a window class, specify ahk_class ExactClassName (shown by Window Spy). To use a process identifier (PID), specify ahk_pid %VarContainingPID%. To minimize a group of windows, specify ahk_group GroupName (WinText, ExcludeTitle, and ExcludeText must be blank in this case). To use a window's unique ID number, specify ahk_id %VarContainingID%. The search can be narrowed by specifying multiple criteria. For example: My File.txt ahk_class Notepad
WinText If present, this parameter must be a substring from a single text element of the target window (as revealed by the included Window Spy utility). Hidden text elements are detected if DetectHiddenText is ON.
ExcludeTitle Windows whose titles include this value will not be considered.
ExcludeText Windows whose text include this value will not be considered.

Remarks

Use WinRestore or WinMaximize to unminimize a window.

If a particular type of window does not respond correctly to WinMinimize, try using the following instead:
PostMessage, 0x112, 0xF020,,, WinTitle, WinText ; 0x112 = WM_SYSCOMMAND, 0xF020 = SC_MINIMIZE

This command operates only upon the topmost matching window except when WinTitle is ahk_group GroupName, in which case all windows in the group are affected.

Window titles and text are case sensitive. Hidden windows are not detected unless DetectHiddenWindows has been turned on.
