In Gliffy for Confluence v6.4 and up, you can search the shape library for keywords to help locate shapes.
The “Search Shapes” field is located in the upper left corner of the drawing canvas above the Shape Libraries:
You can search for any shape in any of the Gliffy shape libraries in this field. The shape library does not have to be showing on the left side for results to pull up.
To search, type in your search parameters and hit “Enter” on your keyboard.
Any results that match your entry will appear below the search box. You can then drag and drop any of these shapes on to your canvas.
