# Managing entities You can add, edit and remove entities from your model as described in the table below. Information note All of the options available in the toolbar are also available from the drop-down menu in the toolbar. This is useful when you reduce the window size, since some of the toolbar buttons - or all of them depending on how small you make the window - will be hidden. The only button that will not be hidden regardless of the eventual window size is the drop-down menu button. Entity management options | To | Do This | | --- | --- | | Add an entity |
