Converting popular abbreviations & other issues
Also, I have Mac OS X 10.6 and using ctrl or just hovering doesn't work. It worked with your example of "12 inches", but for 12 inches in Wikipedia...nothing.
Can you point me to the exact Wikipedia page that didn't work? Sometimes the structure of the document can't be parsed by my script.
As for Ctrl, I'll see if I can add an alternative key binding that works on Mac OS.
