Sibelius 7.5 introduced a "convenient" way to navigate between markers in a score; by clicking on a rehearsal mark in the new Timeline, we're redirected to that part of the score. Please make this navigation independent of the Timeline (which is visual clutter) and mouse-less by introducing a keyboard shortcut for going forward and backward in rehearsal marks. Make it so that both selection and playback start at the rehearsal mark selected by this keystroke. All audio editors I know have the ability of dropping markers on a file and then navigating between them with simple keyboard shortcuts. Navigating through rehearsal marks this easily would be a huge boon for those of us who compose large-scale, multi-sectional pieces with Sibelius.
