This post will need a lot of work.

• Here is a great little reference card.

Here are the key bindings that I find most useful:

• Moving
  • M-g-g Goto line
  • C-<SPC> C-<SPC> – Push this location onto the mark ring.
    • C-u C-<SPC> – Pop the last location in the mark ring and move to it.
• Minibuffer
  • Icicles provides some enhanced history functions.
    • M-p & M-n for previous and next command in history.
• Text:
  • M-q – fill paragraph. Wrap paragraph to “fill-column” characters wide.
