+# selection-to-clipboard
+
+## What it does
+
+This extension includes:
+
+* a content script, "content-script.js", that is injected into all pages
+
+The content script listens for text selections in the page it's attached to and copies the text to the clipboard on mouse-up.
+
+## What it shows
+
+* how to inject content scripts declaratively using manifest.json
+* how to write to the [clipboard](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Interact_with_the_clipboard)
+
+## Note
+* If the `copySelection` function was in a browser event `clipboardWrite` permissions would be required e.g.
+```
+"permissions": ["clipboardWrite"]
+```
+See [Interact with the clipboard](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Interact_with_the_clipboard.)
