Navigation in CMDB Query Builder Use the navigation tools to enlarge or shrink the query, to move the query, or to border a section of the query to run. Use the buttons in the navigation tool as follows: Use the plus sign (+) to increase magnification of the query. Use the minus sign (-) to decrease magnification of the query. Click the center dot to center the query on the canvas. Use the direction arrows to move the query in that direction. Use the selection tool under the navigation tool to toggle between two states: Moving the entire query on the canvas. Bordering a section of the query, which you can then run as a partial query.
