// Modification elements and values:
// Command set that defines which elements in the page are to be modified which way
// Data format:   '[mode]|[id]|[value]#'
//                [mode] can be 'class' or 'id' or 'html'
//                [id] is the identifier, either class name or ID or element name
//                         - class name accessses multiple elements, if any
//                           and additionally needs a tag name, separated by a comma
//                [value] is the per-step-value to add to or to subtract from the current fontSize value
//
//                Examples:
//                In-/decrease DIV elements with class name 'myClass' by 1: 'class,div|myClass|1#'
//                In-/decrease the element with ID 'myElement' by 2: 'id|myElement|2#'
//                In-/decrease all UL elements by 3: 'html|ul|3#'
