Hide Track Markers
This command will temporarily hide any existing Track Markers, and the lines that connect them, that are currently showing in the 'Vector Map' and 'Online Map' tab-pages. The command name will also change to 'Show Track Markers', indicating that this is a non-permanent command, and that clicking 'Show Online Track Markers' will make both markers and lines reappear. If you wish to delete the existing Track Markers and their connecting lines permanently, you should use the 'Clear Track Markers' option.
