How to select unused component?

Hello,

In large files I am facing a problem where I would like to select unused component that were discarted along the process. Is there any shortcut to do this instead of searching for it manually?

If you select a component then hold CTRL-SHIFT and press an arrow key, you select all up/downstream components. So if you select the output component(s) of your graph and hold down CTRL-SHIFT-LEFT, it will select all components that had something to do with the result. You can then drag those components away, leaving only orphans, or components that only read from (and don’t contribute to) the graph. Delete them.

Thanks!
