Backspace producing space on command line #597
Description
I am using tmux zsh with some plugins and iterm 2. I am having problems in command line but not in vim. My backspace key and zsh vi-mode are broken on command line when i use tmux. Let know if my zshrc (at the bottom) is incorrect or if there are incompatible plugins or keybinds listed.
I searched for issues with backspace key and i tried checking and unchecking iterm's "delete key sends ^H" option but it did not change backspace behavior.
i have not put anything in my tmux.conf yet. When i start tmux i get:
/Users/Scott/.zshrc:bindkey:78: cannot bind to an empty key sequence
/Users/Scott/.zshrc:bindkey:79: cannot bind to an empty key sequence
which relates to these lines:
bindkey "$terminfo[kcuu1]" history-substring-search-up
bindkey "$terminfo[kcud1]" history-substring-search-down
commenting out the above two lines removes the tmux startup errors but does not solve backspace or zsh-vi-mode errors
here is the rest of my zshrc:
