Syntax:

$(id):

Start at the element of id id.

<tag.class:n>

Go to the tag tag by class class. The tag and class are both optional (but you must give at least one). Without :n it will select the first element. If n is greater than the number tags, the last tag will be selected. Negative indexes are also allowed, counting from the end. Counting starts at 0, only decendents are matched; if nothing is matched, then this does nothing.

+ and -:

Go to the next/previous sibling; + on the last element, or - on the first element, will do nothing.

p and c:

Select the parent or child of the current node. If c, the first child will be selected. If there is no parent or child, this will do nothing.

#(...):
