Each entry must consist of a name and a value, separated by a space. The name
can have special meanings:

<ul>
    <li>Names beginning with an underscore "_" cause the entry to use the Custom
        Command format, so it supports replacements, but also e.g. requires
        escaping of special characters <code>$</code> and <code>\</code> when
        intended to be used literally. Generally the <code>$1-</code>
        replacement will contain the text given as a parameter when this Preset
        is used.
