Arrange for window to be displayed in normal (non-iconified) form. This is done by mapping the window. If the window has never been mapped then this command will not map the window, but it will ensure that when the window is first mapped it will be displayed in de-iconified form. On Windows, a deiconified window will also be raised and be given the focus (made the active window). Returns an empty string.
On at least Windows 98, this doesn't always avoid the Taskbar. Specifically, if the Taskbar is along the left side of the screen, window may appear underneath the Taskbar. --Chris Nelson 2004-05-20
