If the cursor (the white marker controlled by the Up and Down keys)
marks the file â/usrâ and I press ctrl-j, then the terminal line
underneath the âHint:â shows

marco netuse:~$ usr

Indeed. ctrl-j behaved different than the others, maybe that's
really a terminal issue, but I don't see any reason for the alt key
weirdness.
