Hi Don,
Regarding resetting the amount by which Guide pans when hitting
an arrow key: there's a way to reset this, described at
http://www.projectpluto.com/mar_fmt.htm#panning
Basically, you edit 'startup.mar' and look for line 75. It
will look something like this:
75 panning 0.500000 7.000000 0
The .5 indicates that the chart pans over by half a screen when
an arrow key is hit. Raise or lower that to get more or less
panning with an arrow key.
