navigating COMP markers

People have asked about basic navigation with comp markers in many legacy threads. Hoping their might have been some development that didn't make it into the replies years later. Needing keyboard shortcuts to:

1) Jump to a COMP marker with a two-digit number

2) Jump to next/previous COMP marker (to cycle through markers or as a work-around if no solution to #1. So direct jump will not help in these instances.)

Thanks!
