The tab key became unreliable on my Microsoft Sculpt ergonomic keyboard, so I tried taking the key cap off, and managed to break some part of it. I was unable to get the key cap back on, but if you have something you can do with it, have at it. (I didn't hold onto the parts of the key cap.) I'll leave it on the front porch of 5513 Gettle Ave, free for the taking, first come, first served. No need to contact me; just come grab it.
