About Keybindings

There are a few ways to indicate how and which keys are pressed. The following are all equivalent:

• “Hold the control key, then press x, then release, then release control, then hold shift, press S, release shift”
• Control-X Shift-S
• Control+X Shift+S
• Ctrl-X Shft-X
• Ctrl+X Shft-X
• ^XS
• C-x S

I personally like the last one the most (it’s shortest, and most descriptive). It’s also the way Emacs does it: Emacs Keybindings Reference Card
