Removing individual annotations
To remove annotations, you first need to select the annotations you wish to delete. To select individual annotations, simply left click on them.
Alternatively, to select multiple annotations you can use the select tool in the ribbon, which you can use to click and drag over multiple annotations.
With the annotation selected, you can press the "Delete" key on your keyboard, or click the "Bin" icon to delete the annotation.
You'll then be prompted to confirm the deletion.
