Word choice for scroll bar . . .

[Brian Boisvert <brianb -at- ICONICS -dot- COM>]

     I am updating a manual for a Windows-based product that has an
     explanation of 3 ways to use the scroll bar to pan along a bar graph
     (for example, if the graph is 10 bars long, but you have zoomed-into a
     view with only 4 bars appearing on the screen at a time):

     (1) Single pan - click the left or right arrow on the scroll bar to
     move the graph one bar in the appropriate direction

     (2) Page pan - click inside the scroll bar to the left or right of the
     indicator to move the graph one page in the appropriate direction (one
     page = the current number of bars on the screen).

     **Now, the third option is the one I am questioning:**

     (3) Random pan - click and drag the indicator along the scroll bar to
     view specific areas of the graph.  (for example, move the indicator to
     the center of the scroll bar to view the middle portion of the graph).

     Obviously, these are just rough explanations and I am going to clean
     up the text quite a bit, use graphics, etc., but my problem is with
     the name of the third option.  It really isn't a *random* pan.  Random
     implies that you pan without any clue of what will show up on the
     screen.  Unfortunately, I can think of a word or two to describe what
     is actually occurring.

     Can anyone help?  Does anyone know if Microsoft or some other company
     has a word for this (because all scroll bars do this, MS Word, etc.)

     I am digest, so feel free to respond to me personally in addition to
     your list post.

     Thank you,
     Brian
