This feature is best explained by using an example.
Say you are going to work in a certain area for the day. Your approach in TreeKeeper may begin with running a search for all sites in that area using the Search Tool.
For example, in the screenshot below, you will see a search for all sites in the Northeast Quadrant.
Once the search has been run, you can open the Data Grid using the 
button in the bottom-right corner of the screen. You can then use the Queue by Polygon tool to draw a polygon on the map for sites near your exact location. This will add any site in your selected set within that drawn polygon to the Grid Queue. The Un-Queue By Polygon tool is be used in the same way, but it will remove sites within the drawn polygon from the Grid Queue.
After you have Queued the desired sites, you can click Sort by Queued Data to sort the queued sites to the top of the data grid.
