1. One or more non-transitory tangible computer-readable media having computer-executable instructions for performing a method by running a software program on a computer, the computer operating under an operating system, the method including issuing instructions from the software program comprising:

  • establishing an initial magnification level for a graphic user interface and a pointing indicia whereby the graphic user interface and pointing indicia are magnified and reduced in synchronization;

    establishing a magnification convergence value wherein synchronization between the graphic user interface and the pointing indicia are maintained for magnification levels equal to or less than the magnification convergence value;

    displaying the graphic user interface and pointing indicia at an initial magnification level;

    receiving a new magnification level of the graphic user interface;

    responsive to the new magnification level of the graphic user interface exceeding the convergence value, displaying the graphic user interface at the new magnification level by decoupling synchronization and maintaining the magnification level of the pointing indicia at the magnification convergence value irrespective of continued magnification of the graphic user interface; and

    responsive to the new magnification level of the graphic user interface adjusted below or equal to the convergence value displaying the graphic user interface at the new magnification level by re-coupling synchronization and magnifying the pointing indicia at a factor relative to the graphic user interface magnification level.
