bug: PgUp / PgDown only work on current page

[kiesel]

In default keybindings, PgUp / PgDown scroll a page of lines up or down. It only works on the active view, though. Eg. being on top of all logs and pressing PgDn brings the line selection to the last visible line in current view. Pressing it again does not select the next page's last line but does nothing.

This is unfortunate when you can only move line by line with the down arrow key, since this really takes long then.
