Backspace works, but won't go up or down a line.
set backspace=2 " make backspace work normal (non-vi style) set whichwrap+=<,>,h,l " backspace and cursor keys wrap to next/prev lines
Backspace just puts weird characters in my file.
This is all from :help :fixdel (Vim's help is amazing).
:fix[del] Set the value of 't_kD':
't_kb' is 't_kD' becomes
CTRL-? CTRL-H
not CTRL-? CTRL-?
(CTRL-? is 0177 octal, 0x7f hex) {not in Vi}
If your delete key terminal code is wrong, but the
code for backspace is alright, you can put this in
your .vimrc:
:fixdel
This works no matter what the actual code for
backspace is.
If the backspace key terminal code is wrong you can
use this:
:if &term == "termname"
: set t_kb=^V<BS>
: fixdel
:endif
Where "^V" is CTRL-V and "<BS>" is the backspace key
(don't type four characters!). Replace "termname"
with your terminal name.
If your <Delete> key sends a strange key sequence (not
CTRL-? or CTRL-H) you cannot use ":fixdel". Then use:
:if &term == "termname"
: set t_kD=^V<Delete>
:endif
Where "^V" is CTRL-V and "<Delete>" is the delete key
(don't type eight characters!). Replace "termname"
with your terminal name.
*Linux-backspace*
Note about Linux: By default the backspace key
produces CTRL-?, which is wrong. You can fix it by
putting this line in your rc.local:
echo "keycode 14 = BackSpace" | loadkeys
*NetBSD-backspace*
Note about NetBSD: If your backspace doesn't produce
the right code, try this:
xmodmap -e "keycode 22 = BackSpace"
If this works, add this in your .Xmodmap file:
keysym 22 = BackSpace
You need to restart for this to take effect.
There's also a bug in xterm (at least v224) that may bring other users into the same backspace problem. Here's the link: http://bugs.gentoo.org/show_bug.cgi?id=154090. The information there should be moved into this wiki, but that requires more effort than adding the link.
