Change behavior in sprite lab

I would like to check for if up key is pressed. It seems to be present in behavior. But when i create new behavior , it is not found anywhere…Screenshot_1

Hi!
The is pressed block is actually brand new and hasn’t been added to the toolbox yet. However, if you’re on a laptop there is a workaround to get one into your main work space. Click on the block (as it shows in the behavior definition) to select in yellow. Then use your computer’s keyboard shortcuts for copy and paste (such as ctrl+c and ctrl+v) to copy it into the other workspace. We plan to add this block and other new blocks to the toolbox soon!

Thank you Mike . That was really helpful
