What are `KEYCODE_11` and `KEYCODE_12` for?

Question

Android 5.0 (API level 21) introduces two new keycode symbols to KeyEvent, namely KEYCODE_11 and KEYCODE_12, which ostensibly map to the "11" and "12" keys on the keyboard. I have never seen a keyboard with an 11 or 12 key.

I had thought it might have something to do with watch faces, but then I noticed that there is no KEYCODE_10, making this all the more puzzling.

If I remember correctly, they are used for the HDMI-CEC standard. Since some Android devices have an HDMI out, they can control TV's etc. with this standard. Also check out this commit for Android made last year.
