I was scrolling through Twitter and did something I almost never do and that is using the arrow up and down keys for scrolling. At first everything seemed to be going fine but then I began to realise some issues specially with the arrow down key. I noticed that when I lightly pressed the key it would not register and therefor not scroll down on the page. I was pressing on the key and I felt pushing it down, but it seemed to have not registered. Should I be worried about this? Are any of you having a similar issue? How is the butterfly keyboard treating you in general?
