Object Description
You can assign a description to an object using the Edit->Object Description menu item. This will display the dialog box shown in Figure 8.3. Type the description into the text field, and click on Okay or press Enter.
The description will not appear in the image, but it can be used to locate and select objects on the canvas using the Navigate->Find By Description or Navigate->Add By Description menu items. The description may also be used as a comment when exporting images, depending on the file type. Note that if you assign a description to a group, you will lose the description if you later ungroup it.
