One of the complaints that I often hear from teachers and some students about Chromebooks is that the screen is too small. I agree. There are times when even on my full-size laptop I wish that I had a bit more room to work. That's why when I am writing in Google Docs I often collapse the top menu bar until I need it.
When you're using Google Documents and you want a little more room to view your pages, you can make that space appear with just one click. In the upper, right corner of your screen you will now see an option for "compact mode" in each of your Google Documents. Click the compact mode arrows to collapse the formatting menu and receive about an inch of more space to work in your documents. Below you will see my screenshots showing you where to find the compact mode arrows. (Click the images to view in full size).
