How do you put a link within a paragraph? I'm sure it's easy, but I don't see it!

You go into "text editor" in the paragraph
you then either select some text that you want to be the link (or select all, then at the top of the text editor pane you will see a section called "inline elements"
there is a thing called "link" with a BIG + icon
enter all the details you need there as required
hit the apply button

if you want to change the default colour that is applied or add an underline then you can style that particular text accprdingly

Right click on the paragraph, select Edit text (or select the A with the insertion line), then mark the words that are to be turned into a link. On the right you have the text editor, and right at the top there is a field saying 'Link', with a + to the right of it. Click the +, and there you go.

Ha! Wayan beat me to it
