The input data is placed into the currently active location of the active input buffer, which is determined by previous s, b, or f commands. Any existing data at that location is overwritten. If the pointer is already at the end of the buffer, the input is appended to the end. The colon is the default prompt character.
The input received from the keyboard is placed into the first location of the active input buffer.
