Questions and answers

Which mode should I use?

Use "a piece of a link" for a search term or a file name. Use "a whole web address" only when the text already has https:// and you must keep the colons and slashes.

Why do spaces become %20?

Web addresses cannot contain spaces, so each one is written as %20 (its code number).

Is my text uploaded?

No. It is encoded in your browser.
