# Showing unique descriptive text

Each component has a field called Unique Name, available via the Input Inspector, that you can use to uniquely identify that component. You can use your own numbering system, a combination of numbers and letters, or whatever you wish. You can later access or find each component based on the unique name you have given to the component. This name can also be displayed or hidden on the flowsheet. To display or hide the unique name toggle the button (icon shown below). This button is found on the flowsheet toolbar.
