Mouse functions
---------------

All functions of MapEdit can be called,
just by using the three mouse buttons.
The <left> button is used to change the
main panel items and the field colour
component sliders.
The most interesting mouse functions are
used in the small window containing the
vertical arrows.
<left> will move the left limit arrow on
the map,
updating it's features (number and colour
attributs).
<right> same function as <left>, fbut or
right limit.
<middle> calls the interpolation of the
new interval.
For display reasons, all the 256 colours
are only visible when the cursor is moved
onto the displayed colour map.
