It does if you scroll fast enough, but at a certain speed it reverts to whole lines.

The robot that they used is 14k, down from boston Dynamics 75k, and they also have another which is available for 5k which you possibly might be able to do the same thing with it too.

Outragously expensive is not correct if you ask me.

But to order a list is O(n log n)

In the worst case, you need to insert every element into your set to find out if there's no duplicate hence it'll take O(n log n) too

Not with a hash set - that gives you expected amortized O(1) insertion (yes, both expected and amortized). In contrast, a generalized sort is O(n log n), but you can sort numeric types in O(n).

I strongly recommend binding CTRL to Caps lock. It's pretty ergonomic, and just feels natural. Also, that would force you in a different mindset, aiding in differentiation of your Mac and Linux

This. The MacOS <-> Linux <-> Windows swapping isn’t too difficult, just takes a day or so of training that muscle memory.

I should note to the OP that I almost exclusively use my HHKB[0] for all of those operating systems, which places the CTRL key where the Caps Lock normally is, abstracting caps lock functionality to a function key.

When I do use a different keyboard (or the laptop’s native keyboard), it takes a few minutes to adjust and every now and then I’ll accidentally tap the wrong key, but overall I would say negative impact is negligible

This keyboard has lasted me 4+ years and I use it for gaming, coding, and everything in between. By far my favorite keyboard I have ever used, the toupre keys feel soooo so satisfying.

Yeah I might do that. Currently on Mac I have Caps Lock remapped to a "Hyper" key to act as another layer, so I get "Vim" (jkl; instead of hjkl) arrows. Might move the layer to spacebar instead.
