Clipboard Optimization (Works Everywhere)
This feature lets you optimize text without opening the sidebar — works from any context.
| Step | Action | Windows / Linux | macOS |
|---|---|---|---|
| 1 | Copy the text you want to optimize | Ctrl+C |
⌘C |
| 2 | Press the shortcut to trigger optimization | Ctrl+Alt+M |
⌘⌥M |
| 3 | Paste the optimized result | Ctrl+V |
⌘V |
How it works: The extension reads the clipboard content, sends it to your configured LLM for optimization, and writes the result back to the clipboard.
