How does one send S-RET to Emacs in a terminal?

Question

In org-mode, pressing M-S-RET (meta-shift-return) will create a new TODO on a new line. This key sequence sends M-RET to emacs through my terminal. I've checked this with C-h c ESC-S-RET, which returns M-RET is undefined in the mini-buffer.

I'm using Snow Leopard with Emacs 23.2.1 running in Terminal.app. There is no option to define a RET sequence in the terminal keyboard preferences.

Any idea what's causing the missing SHIFT? Workarounds?

Answer 1

In general, lots of keystrokes are simply impossible to send via a terminal, since terminals emulate an old protocol that only allowed 256 separate keys (or maybe only 128).

Chances are, when you press S-RET, Terminal.app does exactly the same thing as if you'd pressed RET. Thus Emacs has no way to distinguish those two cases.
