In trying to follow the article on VS Code, I managed to foul up the window resolution as you can see in the screenshot below. Searching has not turned up anything to tell me how to get back to a normal resolution. At this zoom level, I can’t see many parts of the screen
Here’s something
Use CTRL + to zoom in
Use CTRL - to zoom out
Edit: VScode can sometimes auto adjust so watch out for that, But it sometimes it fine, so just remember those commands and you should be fine.
