Block Mouse

      This article provides a mechanism for allowing the user to
select a block of the screen which might contain several objects.
This mechanism supports all existing current mouse functions, in
addition to allowing expanded function on a block of objects.

      In today's computer system, the mouse has become an important
asset in interacting with the computer.  Currently, the user may
select only one point or object with the mouse.  In today's
increasingly complex world, a greater flexibility in the amount of
data one can select with a mouse is becoming more vital.

      This article provides a mechanism whereby a simple pointer for
a mouse can be expanded to a mouse pointer for a block of
information.  The methodology described here allows a user to control
2 mouse pointers in a single window which would rotate around an
imaginary focal point.  The upper right mouse is used to denote the
upper left corner of the block to be selected, while the lower left
mouse is used to denote the lower left corner of the block.  Note
that if the distance between the imaginary center point and the 2
mouse pointers is zero, the function will act exactly like a standard
mouse pointer.

      An example would start where the distance between the center
point and the two mouse pointers would be equal to zero.  Thus we
would effectively have a representation of the standard single-point
mouse.  The right button could be used to control the size of the
mo...
