Memex is an extension that allows you to save content from websites, YouTube videos, or tweets. It offers three different ways to save content: using keyboard shortcuts, the mini sidebar, and the popup in the extension menu bar of your browser.

The easiest way to save content with Memex is by using keyboard shortcuts. By default, the keyboard shortcut is option+s on Mac and alt+s on Windows or Linux. Whenever you come across any website or content that you want to save, just press the keyboard shortcut, and Memex will save the content for you.

The second way to save content is by using the mini sidebar. When you hover over the right side of your screen, the mini sidebar will appear. You can then click on the ❤️ button to save the content.

The third way to save content is by using the popup in the extension menu bar of your browser. To access the popup, click on the Memex icon in the menu bar. The popup will then appear, and you can click on the save button to save the content.
