Shift+Enter <-> Enter Swapper Extension

Features

• Swaps the behavior of Shift+Enter and Enter key combinations globally.
  • Pressing Shift+Enter acts like pressing Enter.
  • Pressing Enter acts like pressing Shift+Enter (typically inserting a newline).
• Works within:
  • Textareas (<textarea>)
  • Input fields (<input>) - Note: Shift+Enter often has no default behavior here, so pressing Enter might not do anything visibly different.
  • Contenteditable elements (<div contenteditable="true">, etc.)

Installation

1. Download the extension files (including manifest.json, content/content.js, popup/popup.html, popup/popup.js, and the icons folder).
2. Open your Chrome browser and go to chrome://extensions.
3. Enable "Developer mode" using the toggle switch (usually in the top right corner).
4. Click the "Load unpacked" button.
5. Select the directory containing the downloaded extension files (the shiftEnter directory).
6. The extension should now be active.

Notes

• This extension intercepts keydown events early (capture phase) and prevents default behavior to simulate the swapped key combination.
• For Enter -> Shift+Enter, it manually inserts a newline character in textareas and contenteditable elements to ensure consistent behavior, as simply dispatching the Shift+Enter event might not always produce a newline depending on the specific website's implementation.
