In TeX literal double quotes `"like this"' are seldom used, instead two single quotes are used `"like this"'. To help you insert these efficiently, AUC TeX allows you to continue to press " to insert two single quotes. To get a literal double quote, press " twice.
Inserts the value of TeX-open-quote (normally `"') or
TeX-close-quote (normally `"') depending on the context.
With prefix argument, always inserts `"' characters.
If you include the style file `german' TeX-open-quote and
TeX-close-quote will both be set to `"'.
In AUC TeX, dollar signs should match like they do in TeX. This has been partially implemented, we assume dollar signs always match within a paragraph. The first `$' you insert in a paragraph will do nothing special. The second `$' will match the first. This will be indicated by moving the cursor temporarily over the first dollar sign. If you enter a dollar sign that matches a double dollar sign `$$' AUC TeX will automatically insert two dollar signs. If you enter a second dollar sign that matches a single dollar sign, the single dollar sign will automatically be converted to a double dollar sign.
Show matching dollar sign if this dollar sign end the TeX math mode. Ensure double dollar signs match up correctly by inserting extra dollar signs when needed.
With optional arg, insert that many dollar signs.
To avoid unbalanced braces, it is useful to insert them pairwise. You can do this by typing C-c {.
