Sending keypresses to remote X session over SSH

So I'm sitting in our living room on an Ubuntu laptop working while also watching a TV that is controlled by an Ubuntu HTPC. I have an IR remote set up and can control everything I need to with it, 99% of the time.

However text input on a remote isn't very easy. I don't need to do it very often but when I do, it feels easier to walk 15 feet to plug in a USB keyboard and do it that way. However... I'm criminally and medically lazy and feel walking any distance isn't just unnecessary, it shows the robots they have won. No more I say!

I can SSH into the HTPC fine... Now, how do I send keypresses to that remote computer's X session?

I should mention that I know I could VNC but the TV is 1080p and the laptop is 720p so this introduces some scaling issues. On a technical level, I'd rather a solution that gave me a way to temporarily turn the laptop into a remote keyboard.

Using x2x and some X11 forwarding, I got this to work.

ssh -X htpc x2x -to :0

The only downside currently is I had to bum into a TTY to kill SSH to exit it. Still looking up how to quit when I'm done! Otherwise, it's quite a nice and simple (and shortcuttable) method for transferring input from one computer to another.

Edit: adding -nomouse gave me the ability to close the forwarded x2x window and I can unfocus it to quickly go back to other things without needing to shut the connection down.
