I have a request for 2018 Macbook Pro owners. Can you please press the very bottom right corner of your down arrow key repeatedly, and ensure that each press registers? Video demonstration of issue below.
Backstory: 2016 and 2017 Macbook Pros appear to have had an issue where presses of the half-sized arrow keys do not always register, particularly when the very top of the top arrow or very bottom of the bottom arrow key was pressed. I went through a top case replacement and then a replacement machine (upgrading from a 2016 to a 2017), only to encounter this issue each time. For the first couple of months, I thought I was just having trouble getting used to the small target (i.e. I was missing the key), but after a closer look I noticed that the way I reach down to the arrow keys with my thumb means I'm usually hitting the very edge of the key. What's worse: this does not appear to be connected with dust/debris in the keyboard, but rather is a day-one reproducible issue on many, if not all of these models.
