If you need to access your Event Tags or your Calendar Overlays from your mobile device, you can do so by tapping on the single downward arrow above your calendar and then tapping on the "Tags & Overlays" tab. This will show you a new pop-up screen that will show all of the current Event Tags or Calendar Overlays that you have applied to your calendar.

If you tap on the check boxes next to your tags or overlays, you will either show or hide those tags on your calendar. You can add new or edit Event Tags and Overlays by first clicking on the tab of the group that you want to edit (ex. "Tags" or "Overlays") and then by tapping on the "Modify" or "Add" button at the bottom of the dialog. See the image below:

To close the "Tags & Overlays” dialog, all you need to do is tap on the “X” in the upper right-hand corner of your screen. Closing this screen will return you to your mobile calendar view.
