Re: [O] Guess correct dictionary for Ispell

[Thomas S. Dye]

Aloha Seb,

John Kitchin posted some code to the list a while back that uses
Nicolas' parser for querying the values of keywords and other elements.

I modified his code slightly to include keywords assigned in property
drawers. 

Using this would save your code from having to re-search and presumably
would remove the limitation that the tag be one of the first 8 lines of
the file.

I'm not sure you need this, but I've found it to be generally helpful.

All the best,
Tom
