Hide Online Grid Locators
This command will temporarily hide any existing Grid Locators currently showing in the Online Map tab-page. The command name will also change to 'Show Online Grid Locators', indicating that this is a non-permanent command, and that clicking 'Show Online Grid Locators' will make them reappear. If you wish to delete the existing Grid Locators permanently, you should use the 'Clear Online Grid Locators' option.
