Tagging from the Tackle Chrome extension is really useful when you are working in your Google calendar.

First, you need to download and install the Chrome extension, and you can learn more about it by clicking here.

Once you have it installed, you can tag events in two ways: when you create a new event and when you want to add tags to an existing one.

1. To tag a new event, click on the box beside "Tags" when you're creating the event, and a window with all the event details will open.

2. Just select the one(s) you want to use, and then save the event.

To add tags to an existing event, click on the event to display a pop-up with the event information, and then click on the "Tags" button. A list with all the tags you've created will be displayed, and you can add them by just clicking on them.

You can also tag recurring events using the Chrome extension. Just follow the previous steps, and a message will appear asking if you want to update the following events with the tags you added. Click "Yes," and all the recurring events will be tagged.

Remember, ideally, you may want to add only one tag to an event, and you can add as many properties as you want.
