You can easily filter down the visibility of a set of elements based on a condition by using the show ... when form of the show command

Example
<input type="text" placeholder="Search Quotes..."
     _="on keyup
         if the event's key is 'Escape'
           set my value to ''
           trigger keyup
         else
          show <blockquote/> in #quotes when its textContent contains my value">

Here we do the search on keyup. If the key was an escape, we reset the value of the input and rerun the event, which shows all quotes.
