 Some commands require multiple modifiers, which can also be joined.  All the modifiers in a series add to the first non-modifier. For example, simultaneously pressing Control and Alt and the ``delete`` key can be done via: ``[keyboard.sendString("" + keyboard.modifiers(keyboard._Modifier.control) + keyboard.modifiers(keyboard._Modifier.alt) + keyboard.keys(keyboard._Key.delete))]``
 
 It's also possible to send a sequence of modified keys.  For example, on Macs Command with "c" copies items and Command with "v" pastes a copied items. A copy/paste/paste could be done by:
