macro to format selected text with curly quotes

[ysostarman]

Hi,
I have a set of documents (word 97 - I can't afford the 'new' office versions) that will build into a novel. Since there is a lot of dialogue, I would like to replace the existing straight sets of double quotes with curly 'smart' double quotes. The 'replace as you type' formatting won't work, since the text has already been typed.
Surely there must be a macro to do the following:
1) User selects text (which includes the opening and closing quotes)
2) Running the macro replaces the 'straight' pairs of quotes with 'curly' quotes.


3) It would also be good to have the user select text and then run a macro to surround it with curly quotes! - but this is a separate thing, so no need to bust a gut about it...
