I finally figured out how to launch org-capture from anywhere in
   Windows. I'm using [1]AutoHotKey.
; org-capture
~F9::
If WinExist("ahk_class Emacs")
{
WinActivate
Send ^{c}
Send {c}
}
else
{
Run "C:\emacs-24.0.90\bin\runemacs.exe"
WinWaitActive, emacs
Send ^{c}
Send {c}
}
return
;

   I have Ctrl-c c set up as the org-capture shortcut. I know there's
   another option through something called org-protocol that might work
   better.

   I just got it puzzled out, so I don't know what my mileage will be. But
   I'm pretty jazzed at the prospects. Comments to the code might be
   forthcoming.

   Is this working for you? Do you have a better way to do this?
