Note: if you wish to use any of the meta-characters described above as a literal part of a name, you must escape the character with two backslashes (\). Quotes are optional in most cases, but should be used to avoid conflicts when the value contains characters like "]". For example:

#foo\\:bar
#foo\\[bar\\]
#foo\\.bar
