'''SYNOPSIS'''

'''tk_focusFollowsMouse'''

'''DESCRIPTION'''

'''[tk_focusFollowsMouse]''' changes the focus model for the application to an implicit one where the window under the mouse gets the focus. After this procedure is called, whenever the mouse enters a window Tk will automatically give it the input focus. The focus command may be used to move the focus to a window other than the one under the mouse, but as soon as the mouse moves into a new window the focus will jump to that window. Note: at present there is no built-in support for returning the application to an explicit focus model; to do this you'll have to write a script that deletes the bindings created by tk_focusFollowsMouse.
