You can enter the Tooltips tags directly into your content. However, to save time typing and remembering what the exact syntax is, Tooltips comes with a handy editor button.
With the default editor in Joomla, the editor buttons are located in the top toolbar. If you're using another editor, such as JCE, the buttons may be located below the text input area.
You can use this editor button to place a Tooltips tag block in your article (or other editor fields).
After inserting the code, you can change it in your editor to whatever you desire.
