Sorry for asking so many question.

Anyone know what the 2 things marked are called and what are they for?
A half rest followed by a quarter rest. The first one means you rest for 2 beats (if that's in 4), and the second means to rest for 1 beat. So you rest for a total of 3 beats if you're in four.
Ok, Ive found the quarter rest on GP5, how do I insert the half rest thing in GP5? Also I carn't seem to force beam.

Thanks guys
