[Feature Request] Add PgUp/PgDn buttons or other way to scroll through lists quickly

[m-reiter]

Some plugins offer nearly endless lists of items and scrolling through these takes ages. It would be great if Kore offered a way to navigate through long lists more quickly. PgUp/PgDn buttons are the first thing that come to my mind. Jumping to the first item beginning with a specific letter would be another option.
