This method allows text entry to be performed with a small number of keystrokes.
We call this constant amount of time a keystroke.
However, to accomplish this, additional keystrokes are required.
In some situations, we also have an interpretation of those keystrokes provided by the communication partner in a videotaped session.
In this application the payoff in terms of keystrokes saved may be so large that the overheads can be tolerated.
Since this mapping is many-to-one, most methods for cell phone text entry require multiple keystrokes per character.
This program captured keystrokes as the participant typed and replayed them in real or fast time.
Most spreadsheets come with a macro language that allows them to be controlled by program code, as well as by keystrokes and mouse clicks.
