How to assign an action to the Mac OS X Eject key?

Question

macOS

Good afternoon everyone,
After updating my MBR2011 by replacing the Superdrive with an SSD, the eject button remained, which is empty and no longer useful.
Can you please tell me how to set it to action?
For example: open Finder or Safari
Thank you

Of course you can!
The easiest way is to install BetterTouchTool and assign the desired action to this key.
