Ctrl + n = fast way to a new window before clicking reply. Just close the new window after posting, you will be back where you left off but your new post won't be listed in the forum topics by just using the back button.
Now here's the way I do it. I have a Logitech mouse whose center roller clicks (web wheel) and pops up a circle with links you can add then just click on. I have a link for Other, Products, 12 valve etc. It used to be that there was a jump to box at the end of each TDR page that worked the same as the web wheel, but alas it is gone.
