Latex-Suite ships with the following smart keys:
Smart Backspace.
Pressing <BS> in insert mode checks to see
whether we are just after something like \'{a} and
if so, deletes all of it. i.e, diacritics are treated as single
characters for backspacing.
Smart Quotes.
Pressing " (English double quote) will insert
`` or '' by making an
intelligent guess about whether we intended to open or close a quote.
Smart Space.
Latex-Suite maps the <space> key in such a
way that $ characters are not broken across lines. It does this by
first setting tw=0 so that Vim will not
automatically break lines and then maps the
<space> key to insert newlines keeping
$$'s on the same line.
Smart Dots.
Pressing ... (3 dots) results in
\ldots outside math mode and
\cdots in math mode.
