Be on the lookout
When using the Wait command, students expect a pause in the program. Indeed, sometimes the resulting behavior looks like a pause—when the previous command ended and the execution of the command that follows is delayed. But other times, it looks like the program continues carrying out the previous command without pause.
Note: It is important not to confuse the Wait for block with the Wait Until block.

The Wait Until block is a Stack Decision Maker, working with sensor input. The Wait For block is not a decision maker and does not depend on sensor input.
