They work but need a little more effort than other keys. If you read my posts usually my grammar looks like it goes downhill after one of those. I type fast too which doesn't help. I'm looking at the E on my keyboard right now and it's not at the same level as the other keys. I had to type this really slow to get it right because a lot of e's. I think when I type "the" I just don't give a **** sometimes because the word "the" comes up so much lol.
Time to get a new keyboard, but I just haven't because this works for the most part.
