list item with a yellow border. Pressing tab another time highlights the edit-
able text of the selected item and removes the yellow border. If you click the
plus sign while the currently selected item is surrounded by a yellow border,

List Commands
Figure 9-3 described all the blocks that Scratch added when we created
our dayList. In this section, we’ll look more closely at these blocks to better
understand their function.

Add and Delete
The add command places a new item at the end of a list, while the delete
command removes an item from a specific position. Figure 9-6 shows these
commands in action.
The script first executes the delete command to remove the second
item of the list, which is “Orange.” The script then puts “Lemon” at the
end of the list using the add command.
