The most plausible cause of this problem is that in nn, the
interpretation of arrow keys takes precedence over normal control
characters.

For example, on a WYSE 50 where the left-arrow key send a ^H, the
BACKSPACE key will be interpreted as the "left" key which has nothing
to do with "back-spacing" in nn (it depends on which command you bind
to the left key).

And if the down-arrow sends a ^J or ^M (linefeed or carriage return),
nn will falsely interpret the RETURN key as the "down" key, also when
you enter a : command.  I suspect that is the case with the WYSE.

There are some tricks to get around this problem, but whether they
work or not depend on the version you have.

The Backspace problem can be worked around in 6.3.7 by the command

	set erase-char left

The RETURN problem may be solved by the command

	map key down ^J

which maps the falsely interpreted RETURN key back to a linefeed.


This is a known bug which I hope to get fixed in the soon to be posted
6.3.12, but otherwise will be solved in 6.4 (which will have a new
function key recognition mechanism).
