If parentheses matching for lips is your goal, and you're
already a "vi person", why not use vim? It has support for
syntax highlighting and will clearly show you the parentheses
counterpart. You can also use gvim if you wish to run it on
X. Both programs share the same configuration, so it doesn't
matter if you're using it locally as gvim on X, or vim via
SSH.

And you don't have to learn emacs. ;-)

Regarding a non-working backspace key: First check if it
sends the correct code, it should be ASCII 8, or ^H (Ctrl+H).
That is the default on FreeBSD, of course.

The command

	% stty -a

will tell you the currently active configuration for the
control characters, look for "erase".

Then of course check your mg configuration if it overrides
something. I don't think this is the default, but it could
still be.

For testing, load a file with mg, and press Ctrl+H instead
of backspace. Does it do what it is supposed to do?

Also check your terminal configuration. While xterm usually
applies the FreeBSD OS defaults, terminals primarily for use
with Linux (and therefore integrated in a voluminous desktop
environment) may be configured differently. So if the terminal
emulator you're using can be configured, check its options
as well.



PS.

Please don't assume I'm an "anti-emacs person". In fact,
I'm a "vi person" being too stupid to understand the magic
and the power of emacs, that's why the decision. :-)
