Flip Lock:  Mechanism for Protecting the Setting of a Control

      A method is disclosed for protecting the value of controls so
that their value is not inadvertently changed.  A user can change the
protection on and off directly and graphically.

      This idea states that all controls that can be changed by a
user through mouse actions gain an additional emphasis and visual
enhancement  that either protects that control  or leaves it open to
be changed by a user.  An example of such a visual addition is that
of a flip-down switch.  Imagine a slider control.

      A user can click in the slider's trough to the left or right of
the current bar's value.  This will change the value either larger or
smaller, at the first click, than the previous value.  If a user was
simply trying to surface and make this window active, that would be
an unintended and possibly dangerous side effect of the user's
intention.

      If we added to this control a visual effect, such as a flip
switch, a user could tell at a glance if the control were protected,
and if so, the user would have to unprotect it first before changing
its value.

Figure 1.  Current situation, where a control is not protected.

      If a user clicked on that indicator, it would toggle to the
other state, that in which the user could change the value of that
control at will.
