You have probably noticed that many key words in this document are quoted
in double quotes like ``this is double quoted'' and `this is single
quoted'. By default, the double quote key (") and single quote key (') are
bound to the function text_smart_quote. With this binding and in
wrap mode, the single quote key inserts a single quote with the ``proper''
orientation and the double quote key inserts two single quotes of the
``proper'' direction. To turn this off, rebind the keys to
self_insert_cmd. Some modes already do this (e.g., EDT).
This brings up the question: if the double quote key is bound to
text_smart_quote then how does one insert the character (")? The
most common way is to use the quoted_insert function which, by
default, is bound to the single backquote (`) key. This is the same
mechanism that is used to insert control characters. The other method is
to use the fact that if the preceding character is a backslash, \,
the character simply self inserts. Again, this is ideal for writing
TEX documents.
