Loops are useful for repeating a sequence of steps, such as dance 
moves. To create a loop, select the Orange tab on the lower menu bar. 
Then Drag the Loop to command programming chain.
Then drag your sequence of blocks into the loop. Make sure they are 
attached to the chain and in the correct order. There are many options 
for how long the loop repeats, which can be found by clicking the 
infinity symbol.
