>Use a better setup!

Even if you only use your own computer, customizing the basics is a bit of a trap in many ways.

First you need to find a different setup that is actually better, not just different. Then you need to build muscle memory for it, then you need to never use any other computer because they will not have your setup.

I think getting good at using the defaults is better than changing the defaults. Basically learn to play the guitar, even if it's hard.

I customize things too, but take care to make it additive, not transformative. Aliases, plugins, better software and such are fine, but messing with my muscle memory is just not worth it.

>Also, there are no such symbols even on standard setup

That depends on the standard. In some countries you need two hands to type an @, just to take one example. For US english the numpad is a good example though. Not so easy to find the home keys from the numpad, but your hand passes the arrow keys on the way. :)

>why did you ignore the F6, numpad+ etc hand dance and only focus on the arrow keys?

Because I'm mainly making a counterpoint to your claim that using hjkl was better than using the arrow keys.

It has admittedly grown to a more general anti-bikeshedding rant fuelled by my own bikeshedding regrets - so I better stop here. :)
