Run the selected code directly in the shell (terminal).
If you're curious about the results of your code, or if you wonder if it's grammatically valid, you can check it right away.
However, only some plug-ins (programming languages) are supported.
We currently supportNode.js, Python, and Ruby.
To run it in a shell, right-click on the code you want to check, then click on the [EVAL in REPL] menu. This will immediately open a new terminal window and execute the code for that area.
