How to see the game

I need to ask if there is a way to make game larger to see. I found one way is go to file and look for full screen. That helps me and how hard would it be to make field wide? Text box could be larger to. How do you make text when you write, or other color? Looks like you half to write in black and then preview text?

I believe that there is a keyboard zoom combo of ctrl and plus.

I have been looking and I try that to. So far full screen is only way. Thank you.
