No single shortcut to go to end of file
On my Mac, command+↑ ("command up arrow") takes me to the top of a file/document/webpage. Same sequence with "Down arrow" takes me to the bottom of a file/document/webpage.

If that doesn't work for you, let us know &amp; we'll try to help further.

For future reference, Apple has a list of shortcuts on their support website. It also includes links to app-specific shortcuts.
