Power Move Forward and Back
Orbit Reader's power move commands provide a quick means of
moving/searching through large sections of a file to find a known location in
the document. A power move operates by using boundaries and moving
50% between them with each press of the key command. In essence, by
using a power move to search within a file, you are drilling down to the
information using a binary command. When you press dots 8 2 or dots 8 5,
the Reader moves in the following ways:
On the first press, the cursor moves half way between the current position
and the start (dots 8 2) or end (dots 8 5) of the file, which act as the
boundaries for the power search.
Subsequent presses treat the moved-from position as the new boundary in
that direction. So, if you are at the beginning of the file (or 0%) when you
press the dots 8 5, the Reader moves the cursor to half way between 0%
and 100%. You are now at 50%, and it becomes one of the boundaries. The
initial boundary is at the original position of 0%. Therefore, if you press dots
8 2, you move half way between 50% and 0% to end at 25%. Or, if you
press the dots 8 5, you move half way between 50% and 100% to end at
75%.
Each time you press contiguous dots 8 2 or dots 8 5 keys, the Reader shows
the percentage in the first few cells of the display line and fills the rest with
the text at that position. This continues until you press something other than
dots 8 2 or 8 5 or a Panning key. See
information.
Pressing dots 8 3 repeats a previous search
backwards from the point in the file where
you are. Pressing dots 8 6 searches forward
press dots
again.

If there is no text in the Find Edit buffer, the
