 ## Matchers
 
 Matchers are used to filter nodes by their various attributes (such as values,
-properties, node names, etc). With the exception of `top()`, they are all used
-inside a `[ ]` selector. Some matchers are unary, but most of them involve
+properties, node names, etc). With the exception of `top()` and `()`, they are all
+used inside a `[ ]` selector. Some matchers are unary, but most of them involve
 binary operators.
 
 * `top()`: Returns all toplevel children of the current document.
 * `top() > []`: Equivalent to `top()` on its own.
+* `(foo)`: Selects any element with a tag named `foo`.
+* `()`: Selects any element with any tag.
 * `[val()]`: Selects any element with a value.
 * `[val(1)]`: Selects any element with a second value.
 * `[prop(foo)]`: Selects any element with a property named `foo`.
