 In the terminal, Julia makes great use of both control-key and meta-key bindings. To make the meta-key bindings more accessible, many terminal emulator programs (e.g., `Terminal`, `iTerm`, `xterm`, etc.) allow you to use the alt or option key as meta.  See the section in the manual on [the Julia REPL](https://docs.julialang.org/en/latest/stdlib/REPL/) for more details.
