Chromebook to Mac via Chrome Remote Desktop

I run Scrivener on a Mac Mini, which sits on the desk in my office. Recently, I discovered Chrome Remote Desktop, which allows me to connect to the Mac from my Samsung Chromebook laptop. It works very well… other than some keyboard shortcut re-mappings that are baffling me a bit.

Before I bother going into my specific questions about the shortcut mappings, I’m just wondering if anyone here happens to be running the same sort of setup. If so, I’ll fill in the details.
