Well, the arrow keys are kinda funky, too. Executing :sh and
pressing the up-arrow, then Enter produces this, where the boxes are
on one line and two characters wide.
$ |00| |00| |00| k
|9B| |9B| |9B|
\udc9bku: command not found
I tried looking at the arrow-key keycodes in gvim, but whether
I prefixed the key with ^V or ^K, all I got was the key name, e.g.,
<Up>.
The other arrow keys behave similarly. The characters on the
command line look the same, but the last letter of the command that
bash sees are different.
Key Command
----------- --------
up-arrow \udc9bku
down-arrow \udc9bkd
left-arrow \udc9bkl
right-arrow \udc9bkr
The shifted arrow keys give similar results but also appear
differently on the command line.
Regards,
Gary
