Earlier this week a reader of my weekly newsletter emailed me to ask for advice on how to display a document and countdown timer on the same screen. The idea being that the document is displayed on a large screen via an LCD projector or Chromecast and a small timer is also displayed. The document could be displaying questions for students to answer or procedural steps for them to follow in an alotted amount of time. 

I offered a simple suggestion for displaying the document and a timer on the same screen. My suggestion was to just resize two browser tabs so that the full document and a small timer are displayed on the same screen space. This short video demonstrates how to do that.
