There are so many ways your MacBook's keyboard can get dirty. Naturally occurring oils from your fingertips collect on the keys, dust and dirt particles can gather in the crevices, and drink can spill while you work. We won't even talk about what a moody cat is capable of. Keep dust, dirt, and spills from gumming up your keyboard with a good keyboard cover. Some keyboard covers even have special features, like the MOSISO Silicone Keyboard Coverr (opens in new tab), which has useful keyboard shortcuts printed on it. Before purchasing, make sure your model MacBook (Air or Pro) matches the cover you're getting. Keyboard covers are not one-size-fits-all.

The MOSISO Silicone Keyboard Cover is more than just a protective keyboard cover; it's actually a keyboard shortcut cheat sheet. I don't know about you, but other than the few I use frequently, I can never remember the MacOS keyboard shortcuts. I know there are so many good ones that I should use more often, but I can't be bothered to google them each time I need them. This keyboard cover has them all printed right there for easy access. You can choose from three different colorways. Note that this cover is just for the 2016-2019 MacBook Pro models, though it should fit the 2020 models as well.
This one protects your MacBook's keyboard and gives you keyboard shortcuts to boot.
