ok, this is something i've never seen,i'm typing this on wordpad and copying and pasting it for this post.when i try to type in search or ANYTHING else in IE and hit certain keystrokes,it erases what i typed and brings down the web address bar with the single letter in it i type in.i tried reinstalling windows and it didn't help, i RAN VIRUS scan, it didn't detect anything it started working right for a couple days now its doing it again.this will be a serious challenge for somebody to figure out.this is what i typed after i deleted the extra letters in wordpad following it is  what it looks like when i type it unedited.

Did you try another keyboard?
What Windows version?I thought the spelling of "feint" in the title was funny considering the topic. (It's f-a-i-n-t) Or is it MEANT to be a joke?

I would try another keyboard too.
