| - | Components all have an address. This address is a UUID, a unique identifier. In most cases it is OK to abbreviate these addresses. For example to get the full address from an abbreviated one you can use `component.get`. To get the address of any block in particular, you can use the [[:analyzer|Analyzer]] by holding the control key while right clicking the block. | + | Components all have an address.
