XTHIS

A tiny Chrome extension that opens X.com's post composer pre-filled with the text you've highlighted and the URL of the page you're on. One step, no copy-paste.

Triggers (all do the same thing):

• Toolbar icon click
• Right-click → Post to X with XTHIS
• Ctrl+Shift+X or Option+Shift+X

Install

From source (until the Chrome Web Store listing is live):

1. Download or clone this repo.
2. Open chrome://extensions, enable Developer Mode.
3. Load unpacked → pick the xthis/ folder.
4. Pin the icon. That's it.

See xthis/README.md for the per-extension install details, shortcut rebinding, and asset notes.
