Can't write bold text :(

Date: 8/30/2018

So multiple guys and I are on a beach, while one guy is in a raft in the sea close to us. He is facing us and stays on the same spot. I have the task to write a text in part bold and part cursive and then part bold again. I have the choice to write it in code editor or in smart text editor. I cant get the nold and i am not happy about that.
