The text that displays inside of an appointment box can be customized through the template editor. Like our other templates you can use keywords to control how they are displayed. Here's how:
Click on Settings > General > Calendar > Customize It
The right panel displays a list of keywords you can put in the appointment box
Place your mouse in the left pane where you would like that keyword to show
Then click on the keyword in the right panel to copy it into the template
Click Save
Click on Scheduling to see the new appointment box details
