删除（转发）字符iTerm2 OSX

Question

I am using iTerm2 on OSX, and I am using an external keyboard with a Del (not to be confused with Backspace ). The Del key works fine in OSX but in Terminal and iTerm, it inserts "~" instead of deleting forwards one character. This is easily fixable in Terminal, but in iTerm, there is no key binding or escape sequence that allows me to delete a character to the right of the cursor (the equivalent Unix command is Ctrl D ). Is there any way I can simulate deleting forwards one character in iTerm?

Answer 1

If you are using zsh, try adding these lines to your ~/.zshrc file, then close and reopen the terminal:

bindkey    "^[[3~"          delete-char
bindkey    "^[3;5~"         delete-char

These should enable your delete key on any keyboard, without manual keyboard mappings to the hex command 0x04 , which has the problem that it closes the session if the input is empty.

Why this? Because it seems that zsh doesn't read /etc/inputrc with the key bindings by default.

Answer 2

You can add a iTerm Keyboard Mapping in Global Preferences or a Profile-based one for the key to send a Ctrl-D (0x04)

ie: Here I am mapping Ctrl-Delete to Erase (Ctrl-D/0x04) like an Extended Keyboard's Del key:

Like Gajus said, using Ctrl-D to delete one backspace forward also closes the terminal tab if there's no input which can be very frustrating.

I am using zsh, but adding the lines ricpacca suggested to .zshrc didn't work for me.

What I did instead is to map Ctrl-Delete to send the hex codes "0x06 0x08".
0x06 translates to "move one character forward", and 0x08 is just a normal backspace.

Thought I'd share my solution for any other frustrated iTerm2 users that scoured the internet to no avail.
