What is the symbol/s for spacebar press when using the `screen stuff` command?

I have a screen command as such..

screen -S sessionname -X stuff 'spacebar'

I want to replace "spacebar" with the appropriate symbol/s to emulate a spacebar press. I would also like to know what the symbol/s are for the arrows to. I couldn't find a reference after multiple searches.

Solution

The symbol for the spacebar is a space:

screen -S sessionname -X stuff ' '
