I don't play an instrument, but this is pretty awesome. 

Minor update to the Emacs Calc Quick Reference Guide. This release adds a section for statistics operations on data vectors, and fixes some minor typos and stuff.

See https://github.com/SueDNymme/emacs-calc-qref/releases for the latest release (including pre-made PDF editions).

Hello Emacs Calc fans!  I have made a quick reference guide to this fine tool. It's no simple card, but a little booklet to keep near your computer. I've been adding to it for years, but finally made it public (with the encouragement of jcs at Irreal).

It's now available on GitHub at https://github.com/SueDNymme/emacs-calc-qref  — and with pre-made PDF versions at https://github.com/SueDNymme/emacs-calc-qref/releases

I just discovered a cool hack, and I thought I'd share.

I mostly use Emacs under Windows. Recently I found out how to remap keys via the Registry (see http://www.howtogeek.com/howto/windows-vista/disable-caps-lock-key-in-windows-vista/).

I remapped the (useless) CapsLock key to be the Windows-Right-Click key, which I guess is formally called the "Application" key. (Also I mapped NumLock to be CapsLock, in case I ever need that, because if there's one thing that's even less useful than CapsLock on a full-sized keyboard, it's NumLock). Note that you have to reboot for the mapping to take effect.

Finally, I added this line to my emacs init file:
    (setq w32-apps-modifier 'hyper)

Now my CapsLock key is a fully-functional Hyper modifier! A whole keyboard full of mappings awaits. It even works in combinations, such as C-H-a and H-M-b.
