@,
@newKey("secondKey", "")
@    .test.pressed( getVar("firstKeyPressed") )
@    .success( newText("same", "So, you pressed the same key twice!") )

• First creates a Var element named firstKeyPressed and then prints a text inviting to press any key. When a key is pressed, it is stored in the Var element (.set command). The Var element is then used to print which key was pressed, and when a second key is pressed, it is used to test that the same key was pressed.
