#19 Scroll up when "B" is pressed

[GI]

Using Space/Backspace to read a document is quite inconvenient, since the backspace key is quite far away from the space bar. I usually use Page Up / Page Down to read PDF files (kpdf), but djview uses that to skip forward/backward one page.

So the (trivial) attached patch scrolls up when "B" is pressed, so I can use "Space/B" to read my documents (like in "less").

If you later find a different use for the "B" key, please consider adding some keyboard friendly way of reading documents (e.g. Page up / pagedown).
