My delete key was stuck and I am not sure how it got stuck in the first place. It's been fixed. What I did was pressed the key on the edge it was stuck with a little more pressure than a light tap. It actually worked. I am going to clean my keyboard with the walrus attachment on my vacuum as soon as I have the house to myself so I don't disturb someone. (I read somewhere online that canned air wasn't recommended.) I just wanted to share.
