Data Entry on terminal screens involved positioning the cursor on the screen at various places, displaying pieces of information in bold or reverse text.

Even with processors running at multigigahertz speeds, calling an external command multiple times can produce a noticeable delay. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
