Text Entry Boxes (TEBs) allows your learners to type directly into your eLearning lesson. Personally, I think TEBs offer the highest level of interactivity you can add to a lesson without the need for advanced programming skills. To add a TEB to a lesson, simply choose Insert > Standard Objects > Text Entry Box.
The assumed default usage of a TEB is short bursts of information entered by your learner. For instance, many people use TEBs to simulate access into an application (the learner is asked to type a username and/or a password). However, there are instances where you might want the learner to type a sentence or two (to simulate the use of a word processor or a text field where multiple lines of text are acceptable).
In the image below, I previewed a lesson and typed a fairly long sentence into a TEB. Notice that once I reached the right side of the TEB, instead of wrapping to a second or third line, the text continued to move right.
