comint-accumulatecomint-accumulate is an interactive compiled Lisp function in `
comint.el'. (comint-accumulate) Accumulate a line to send as input along with more lines. This inserts a newline so that you can enter more text to be sent along with this line. Use M-x comint-send-input to send all the accumulated input, at once. The entire accumulated text becomes one item in the input history when you send it.
