    // Get search input, from selection or prompt
    let input = function(){
    
      // First attempt to get input from selection
      let find = editor.getSelectedText(),
          start = draft.selectionStart,
          length = draft.selectionLength,
          end = start + length;
    
      // If there is none, try the prompt
      if (!find) {
    
        // Create prompt UI
        let p = Prompt.create();
        p.title = "Find Selection";
        p.isCancellable = false;
        p.addTextField("find", "", "", { 
          wantsFocus: true
        });
        p.addButton("Find");
    
        // Set values from prompt
        if (p.show()) {
          find = p.fieldValues["find"],
          start = editor.getSelectedRange()[0],
          length = find.length,
          end = start + length;
        }
      }
      
      // Return values as array
      return [ find, start, length, end ];
    }
    
    // Search draft for selection
    let search = function(){
    
      // Get search input, from selection or prompt
      let [ find, start, length, end ] = input();
      
      // Ensure the keyboard is active for selection
      editor.activate()
    
      // Find next occurence
      start = draft.content.indexOf( find, end );  
      
      // If none, try again from beginning
      if ( start < 0 ) {
        start = draft.content.indexOf( find, 0 );
      }
      
      // Update the selection to the next occurence
      if ( start > 0 ) {
        editor.setSelectedRange( start, length );
      }
