Ability to jump to next/previous page in note preview

Currently the up and down arrows scroll through a list of notes, and right and left arrows scroll line by line through the text of an individual note. How about adding ctrl-left and ctrl-right to jump the number of lines set in 'Preview Text Lines, Max'? This simple addition might satisfy those who want some sort of non-editor preview.
