Note: The Meta key is Alt or Esc. Ctrl is abbreviated as C. So the keystrokes C-x C-c means hold down Ctrl while you first press the letter x, release x, and then while still holding Ctrl press the letter c (this command will exit Emacs).
Once within Emacs, some example commands:
C-h t

C-x C-s

XEmacs is a program that works very similarly to Emacs but does have some differences. You are encouraged to evaluate both and decide which you prefer. XEmacs is available as the command xemacs.
