If you're looking to turn a word or sentence into a hyperlink, simply select it and click on the linking tool. You'll be asked to type in a URL which you then may insert.
Once you've typed in text or an e-mail address that you'd like to link, select it and click on the linking tool.
Then, type in 'mailto:' and an e-mail address (for example, mailto: firstname.lastname@example.org). An 'Link to email' option will appear from the drop-down menu, select it and your text will be available as an e-mail link.
To add a link to any of the uploaded files, first type the text and highlight it. Then click "Insert a link" on the text editor toolbar to open the link tool: as you start typing the file name, you will be presented with a list of links to the uploaded files. Click on any of them to apply the link to the selected text.
To link an image, first drag the image into your text content area from the 'Files' menu.
Then, click on the image and select the linking tool from the toolbar. Type in an URL, insert it and your image will act as a link.
Every time you enter a link to either your text, image or as a document, a drop-down option named 'Link to' will appear. By selecting it, it will be opened in a new window when clicked.
Click on the existing link and select the linking tool from the toolbar. The linking tool will open up and you'll be able to change the URL and confirm it by clicking 'Change'.
In case you'd like to remove the link, again select it and open the linking tool from the toolbar. Then just delete it, click on 'Change' and the link will be removed.
