Majorly inconvenient.  At first I let it be, when xz couldn't decrompress
the file.  But I wanted to investigate the competitors of nano, so I tried
again, and finally figured out that I needed lzip for decompression.  Bwuh.

What problems or defects does xz have?

Very, very few people will be interested in moe, so showcasing lzip there
has just about zero effect.  The major effect it has is to stop people from
trying moe, because it's zipped in a by default inaccessible format.

If you want to showcase lzip, you should get a major package like grep
or coreutils to adopt it.

Oh, ^H was quite intuitive.  Much more than F1.  Besides, F1 in my
terminal emulator calls up the manual of that Terminal.  :|

In a Gnome Terminal.

Ah, yes, a Linux console is completely handicapped: for the Arrow
keys it completely ignores the modifiers.

Konsole is another deficient terminal.  I pray for its users that
those key combos can be reassigned.

Version 5.7 on the machine that I normally use.

Just about all editors do this.  Emacs, Vim, Pico, nano, Gedit, Geany.
And all word processors that I know (LibreOffice Writer, for example).
(Not on a Linux console, of course, but on a Gnome Terminal yes.)
The only one that doesn't do it is Joe.

A Ctrl+Left always lands on the first character of a word.  The behavior
for a Ctrl+Right differs: Vim, Pico, nano, dex, Minimum Profit and Writer
all go to the first character of the next word; Emacs, Gedit and Geany
land right after the last character of the current word.
