Inserting a Link
First type out the name of the link - It is best to use a meaningful name, rather than 'Click me' or 'Click here'
Then highlight name of your link, and then click on the 'Insert/edit link' button
In the popup window that comes up, you can either:
begin typing the name of the file
or
click on the Media Library button to search for the file. If it already exist choose it from the library. If it does not exist click on the Browse button in the Add file section to add a new file.
Unlink Your Link
To get rid of the link you have on your page, highlight the link and click on the 'Unlink' button.
