Someone on one of the Microsoft Newsgroups asked how to get AutoCorrect to make an M-dash (dash the width of a capital M). I typed up an answer saying that it already did. But then I checked and was wrong. Turns out that it gives an n-dash to replace one hyphen or two. So, here’s what I ended up posting. Thought I would share this tidbit and show off my ignorance a little more (in case there were any doubts).
I thought it did this by default! Tried [space]–[space]text[space] and I
was wrong – it’s an n-dash, the same as [space]-[space]text[space].
Anyway,
to fix this, use Insert => Symbol… => Special Characters (tab) to insert
an M-dash. Then select that M-dash and use Tools => AutoCorrect to get to
the AutoCorrect dialog. Type in your two dashes as the text to be replaced
and you should be all set.
Hope this is of help to somebody else.
