hud_radar_show_hold
This will show the name of all the important items on the map (RL, LG, GL, SNG, Quad, Pent, Ring, Suit, Mega, Armors). A circle is drawn around the items, the team who has the highest weight inside this area is considered to be holding that particular item. See the teamholdinfo hud item.
Show the item names and circle on the radar.
Don't show the items and circles on the radar.
It is not recommended to have this visible at all times. Instead it's meant for a quick glance to know which item is named what when using the Teamholdbarinfo hud item. For instance if the map has two YA's, one is named YA and the other YA2. Use this feature to see which is which.
