Keyboard Shortcuts on Mac through Chromebook

So, I've fallen in love with my Chrombook and the ability to log into my desktop at home, wherever I'm at! However, I'm running into a problem and I'm not certain if it's a bug, lack of functionality, or my own incompetence.

I cannot use shortcut keys while working remotely on a Mac computer. I know that the Chromebook is missing a few keys, but I cannot perform simple actions such as cut or paste. Is there a list of translated keyboard shortcuts out there, do I need to set this up on my own for remote sessions, or is there a known issue?

Thanks in advance!
