So, this page will have the most frequent and useful Emacs shortcuts for ME! I have to emphasis this since many people use Emacs for many different things. I like writing in Emacs, and occasionally reading too.
I highly recommend doing the Emacs help/tutorial thing, before you dive in. It has some basics in it, that I probably won't repeat it here.

C-x k You can kill the current buffer (just hit Enter), or any buffer.
C-x C-f Find (or Open) buffer.
C-x C-s Save the current buffer.
C-x C-w Save the current buffer with a new name. Basically a save as function.
C-x 0 If you have multiple buffer open in a window (split), you can close the given buffer with this, and the split space also closes.
M-w Copy the selected text to clipboard.
C-w Cut the selected text to clipboard.
C-y Paste text from the clipboard.
