page buttons when selecting effect: bug or intended?

  • Never noticed this before but when choosing an effect for a stomp/slot using the browse knob (which can be further navigated by the up/down/left/right buttons) the "page <" and "page >" buttons illuminate and change their appearance when pressed but have no apparent function when pressed.
    Is this a fault or how its intended to be?
    would be really useful if they skipped categories or by first letter name, as when choosing rigs to make for quicker selection.
