# Send Shortcut Prompt

> A chat-style message composer with an auto-growing textarea and a toggle that lets users choose whether Enter sends the message (Shift+Enter for a new line) or Cmd/Ctrl+Enter sends it instead, with a keyboard hint that updates to match. Ported from the original HTML/CSS/JS by MM Rahman Bappi (100 Free AI UI Components, MIT licensed).
