Oh ok thanks! I saw some videos had the tags not on there or something else.A "tag" is kind of a convoluted scanner bank/channel number so a user can go directly to a specific frequency for a non trunked system or talk group on a trunked system for monitoring purposes. Kind of supporting the "old school" scanner memory idea.
A user programmable field/A short cut to something you want to specifically monitor.
