       tk_focusFollowsMouse
_________________________________________________________________

DESCRIPTION
       tk_focusNext is a utility procedure used for  keyboard  traversal.   It
       returns	the  ``next''  window  after window in focus order.  The focus
       order is determined by the stacking order of windows and the  structure
       of  the	window hierarchy.  Among siblings, the focus order is the same
       as the stacking order, with the lowest window being first.  If a window
       has  children,  the  window  is visited first, followed by its children
       (recursively), followed by its next sibling.  Top-level	windows	 other
       than window are skipped, so that tk_focusNext never returns a window in
       a different top-level from window.

       After computing the next window,	 tk_focusNext  examines	 the  window's
       -takefocus  option  to  see  whether  it	 should	 be  skipped.	If so,
       tk_focusNext continues on to the next window in the focus order,	 until
       it eventually finds a window that will accept the focus or returns back
       to window.

       tk_focusPrev is similar to tk_focusNext except that it returns the win-
       dow just before window in the focus order.

       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 return-
       ing the application to an explicit focus model;	to do this you'll have
       to write a script that deletes the bindings created by tk_focusFollows-
       Mouse.
