How to fix strange backspace behaviour with urxvt + zsh?
Solution 1:
Try adding the following to your .zshrc:
TERM=xterm
Solution 2:
In zsh, what does bindkey | grep delete say? These are the lines I get:
"^D" delete-char-or-list
"^H" backward-delete-char
"^[3;5~" delete-char
"^[[3~" delete-char
"^?" backward-delete-char
You should have "^?" as that represents backspace. If not... you can call bindkey "^?" backward-delete-char at the zsh prompt to put it in.
Does that resolve the problem?
