1) Go to your inbox.
2) Click on a part of the screen which is not a button.
3) Press the Tab key 58-60 times (I would make a video, but you can count, or just look for the
CheckBox.
4) Click on that CheckBox.
5) Ctrl-F (find text: "Selected Messages")
6) Click on the ListBox to the right of the "Selected Messages" text string, which should say, "Move to folder...", change the ListBox's output to "Delete".
7) Click the "Go" button.
8) If nothing happened, repeat from step 1.
