I was in Toledo, Ohio over the weekend for a ceremony, and I impressed the hell out of my dad with Google Now. We were driving in unknown territory, and he was fretting about how we were going to find our way back. I said don't worry, I've got my phone. He said, "Oh, does it have GPS? Will you be able to find the university?" I picked up my phone and said, "Google. Give me directions from my location to the University of Toledo Health Sciences campus." In less than five seconds the whole route was displayed graphically right there on a map. It was beautiful. :-)

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

Can you try this, please:

Run Ghostscript interactively. Then at the gs prompt, type "/Symbol findfont" and hit enter.  Let me know if it loads okay, or if you get any errors.

$ gs
GS> /Symbol findfont

Customization  - 
 
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.

On a ThinkPad, I find these two definitions useful:

   (global-set-key [XF86Back] 'previous-buffer)
   (global-set-key [XF86Forward] 'next-buffer)

so, M-x describe-key, push your favorite unused key to see what Emacs sees when the key is pressed .. use the name to bind the key to a function.
