I do this all the time. All of my search queries are like:
amazon.logitech.mouse
Etc.....
Also when using the regular keyboard I keep hitting the damn emoticon button instead of the punctuation key, especially when typing one-handed. They really haven't thought this through in terms of usability. You can disable the emoticon key but it just replaces it with something else (I cannot remember what) which brings up a pop up dialog when you hit it. They should give you the option of removing the emoticon key and making the space bar bigger.
