string: The id of the marker. This is either the text name, the internal id, or a regular expression. (See id, below)
boolean: If true, position the marker at the center of the map (optional)
boolean: Show the marker on single column displays (generally phones)
Select a private or public marker. On large displays (two column layout), the marker will be shown on the Markers tab if a private marker or on the Info tab, if a public marker. For single column displays (phones, generally), the tab is displayed only if the "showIfMobile" option is true.
