As an English teacher, it is often a requirement to show two documents together on the same screen. When conducting a reading exercise you might want to have the reading text on the left and the questions on the right. An ideal application for this is NotePad++. This is free software, downloadable from many sites. It is easy to use, but you will need to spend five or ten minutes exploring the features initially
For presentations, you need to have it operating in text mode. This is how you can use it with a split-screen, with both sides scrolling independently.
