Popup Text Copier is a free Chrome extension designed to enhance text input efficiency. This add-on allows users to quickly open a text input box using a designated shortcut key. Once the user has entered their text, pressing Ctrl+Enter will copy the content to the clipboard and close the popup. This functionality is particularly useful in chat applications like ChatGPT, where it serves as a safeguard against accidental message sending due to Enter key mispresses.

To set up the extension, users must assign their preferred shortcut key in Chrome settings upon first launch, with Ctrl+Shift+Q recommended for optimal use. This tool is ideal for anyone looking to improve their text handling in online conversations or applications, making it a valuable addition to any user's browser toolkit.
