How to get it: open the page in a computer browser, press Ctrl+U (or ⌘+Option+U on Mac), select all and copy. Browsers don't let one website read another website directly, so pasting keeps it private and works for any page.
Questions
Good to know
Is my text sent anywhere?
No. Everything happens in your browser on your own device. Nothing you type is sent to a server or saved.
Why can't I just type the address?
For safety, browsers block one website from reading another. Pasting the page code works everywhere and keeps everything on your device.
