Instructions for just Terminal instead of iTerm2

[alper]

There's this bit from the docs:

NOTE: On OS X, Alt-c (Option-c) types ç by default. In iTerm2, you can send the right escape sequence with Esc-c. If you configure the option key to act as +Esc (iTerm2 Preferences > Profiles > Default > Keys > Left option (⌥) acts as: > +Esc), then alt-c will work for fzf as documented.

and I'm not sure what is being suggested here nor how to translate it to the standard system Terminal.app.
