Here's how to delete a Task Shortcut on the Topics view.
First, go to the Topics view.
Topics
Accounts
Tasks
Trails
Keys
Settings
In the Topics view, you will find the delete button in the top right corner.
After clicking the delete Shortcuts button, another delete button appears inside each shortcut.
Done.
It's good to know that if you accidentally delete a Task Shortcut, you can always recreate it. If that happens, just create it again by selecting it from the Shortcuts list. You will have the same Task Shortcut as before.
To do this, your current Robogator instance must have designer mode turned on.
