Since 15.2 TiVo now supports any USB keyboard plugged into the back: Enter = Select Esc = Clear (danger!) F1 = TiVo F2 = LiveTV F3 = Guide F4 = CLEAR (danger!) F5 = Thumbs Up F6 = Thumbs Down F7 = Channel Up F8 = Channel Down F9 = Record F10 = Info Odd choices for ESC and F4 to be clear, and more than a little dangerous when in "my shows" Up and down arrows work as expected, left arrow is "Back", right arrow is "select". Pressing F11 gave me a surprise though: Yep, the old SD menu is still there, and quite a bit quicker than the HD menus. Also some more options: Kidzone and guru guides just say network error though. I was hoping that watch liveTV would bring up the old live tv guide, but no luck.
