Most AutoCAD Map 3D commands are wildcard character-enabled. To use a wildcard character as a literal character, precede the wildcard character with a back quote (`). For example, if you have a layer named "Floor Plan #1," from which you want to query some objects, type Floor Plan `#1 when you create the query. If you select the name from a list box, the back quote is added automatically to the text that appears in any corresponding edit box. The wildcard characters for which this is valid include #, @, .(period), ~.
