+:::{note}
+The `withName` selector applies to a process even when it is included from a module under an alias. For example, `withName: hello` will apply to any process originally defined as `hello`, regardless of whether it is included under an alias. Similarly, it will not apply to any process not originally defined as `hello`, even if it is included under the alias `hello`.

 :::{tip}
 Label and process names do not need to be enclosed with quotes, provided the name does not include special characters (`-`, `!`, etc) and is not a keyword or a built-in type identifier. When in doubt, you can enclose the label name or process name with single or double quotes.
