Description
ChatGPT Enter Key Control is a Chrome / Edge extension that helps prevent accidental Enter-key sends while writing in ChatGPT.
When writing long prompts, email drafts, business text, or longer messages in ChatGPT, it is easy to send a message by mistake when you only meant to add a new line. This extension adjusts the Enter key behavior so you can write more calmly, like in a regular text editor.
NEW · v1.3.0
Fix for IME issues after multi-line paste
In some environments, ChatGPT can show an input bug after pasting multi-line text, where Japanese or other IME input becomes unstable or characters appear in the wrong order.
Version 1.3.0 adjusts how supported plain multi-line text is pasted to reduce this issue and make it easier to continue typing with an IME.
The extension does not override ChatGPT's normal paste behavior for HTML, rich text, images, files, URLs, or other unsupported paste types.
Use Enter for line breaks
Use the Enter key to insert line breaks, making it easier to write longer questions, notes, and prompts.
Send with Shift / Ctrl / Cmd + Enter
Send messages with Shift+Enter, Ctrl+Enter, or Cmd+Enter. This clearly separates line breaks from sending and helps reduce accidental submissions while writing longer text.
Supports Mac keyboards
On Mac, you can send with Cmd+Enter, so the extension feels natural to use with Mac keyboards.
