Which components of a FDIO are used to compose and edit outgoing messages?

Explanation:
The ability to draft and modify messages relies on seeing what you’re creating and providing the means to input changes. The keyboard lets you type, delete, and edit as you go, while the display shows the message in real time so you can review and adjust before sending. The printer would only produce a physical copy after the fact, not help you compose. The modem is for transmitting the message, not for composing it. The RCU cabinet assembly is the hardware housing, not an operator control for drafting. So the tools you use during drafting are the display and the keyboard.
