Most of the functional controls have the option to Edit, Delete or Duplicate.
Whenever we click on Right click on the specific control thats been added to the wireframe section, we can see a dropdown list.
Edit: Can be used to edit the name of the control if there's a text.
For eg. a button with text Button can be editable and can be changed from Button to Save.
Delete: Can be used to delete the added control. We can also delete the control by just clicking on the control, so that the control is selected and then click on the Delete. The control is deleted.
Duplicate: Whenever you want to create the same control e.g. let's say button control with same button text, same text size and color. Clicking on Duplicate adds a new control which is exactly the clone of previous control. This saves a lot of time. This is quite handy.
