I’m half-kidding about this though. I get that the stuff you mentioned are a lot more important. These are the reasons I started exercising and using break timers.
But the thing with learning keyboard driven workflow is that you tend to develop a habit of spam pressing keys if you can’t immediately think of a way to something with less keyword. Especially in vim. Because if I’m not always pressing something, I don’t feel like an expert enough, damn it! So I resorted to spamming hjkl, lol.
When my RSI problems start to develop. I had to really focus and change that habit to slow down and think of a way to press less keys. But still I stopped using vim key equivalents on browsers though, mouse scrolling relaxes my fingers a bit more than key pressing.
