Mechanical Keyboards

I do.

Usually you've clicked on the cells already, or use F5 to enter them.

Although my colleague alternates his mousehand half way through the day, so presumably all ambimousetrous use their left hand when numberpading.

I go back and forth on getting a nice small mechanical keyboard, but honestly I like having the numberpad. The laptop I'm using WFH has one, and I notice the lack of one on my personal one.
