In zsh, whenever I press Fn+Delete (which is forward delete) a tilde (~) gets inserted. This indicates zsh doesn't have the key bound.
How do I bind it, and make it behave normally (delete in front of the cursor)?

First figure out what sequence it generates.
echo "CtrlVFnDelete" | od -c
Then bind that sequence using the normal zsh bind mechanism.

10@rixth: It's not actually outputting only a tilde. You can't use
echo "~", you have to actually follow the directions that Ignacio gave you. On my system, it's^[[3~(or asodoutputs:033 [ 3 ~). So the command would bebindkey "^[[3~" delete-charwhich would go in your~/.zshrc. Aug 2, 2010 at 1:05 -
2To clarify the above,
ctrl-vis a special escape sequence that means "insert the next character I press as a literal unescaped character, instead of doing whatever it usually does." Meaning that it doesn't get converted to~, but stays as the escape sequence.– NHDalyMay 23, 2016 at 23:38 -
I don't understand how to use the output of the above to derive the bindkey. My output is
0000000 C t r l V F n D e l e t e \n 0000016. Jun 22, 2016 at 13:32
For me the above didn't do the trick so I added the following key binding to my ~/.zshrc:
bindkey "\e[3~" delete-char
FYI: I am on a Mac (High Sierra).

And how to know the code for any other key I want to bind, e.g. Fn+F1? so that I can set the corresponding codes in my
~/.zshrc. Mar 29, 2018 at 17:34 -

bindkey 'CtrlvFnDelete' delete-char
This will bind Fn+Delete to delete forward a single character. If the above is not clear, you need to type Ctrl+v, Fn+Delete between typing the quotes. Ctrl+v allows you type the literal escape escape sequence of whatever key comes after it.
You can put this line in your ~/.zshrc file.
