Keystroke log
The TNC stores keystrokes and important events (e.g. system startup)
in a keystroke log. The capacity of the keystroke log is limited. If the
keystroke log is full, the control switches to a second keystroke log. If
this second file becomes full, the first keystroke log is cleared and
written to again, and so on. To view the keystroke history, switch
between CURRENT FILE and PREVIOUS FILE.

The TNC saves each key pressed during operation in a keystroke log.
The oldest entry is at the beginning, and the most recent entry is at
the end of the file.
