It's better to have an easy way to hold a mouse button via keyboard with your left hand and continue to use one finger on the touchpad rather than do the whole three fingers to drag
Honestly? Only three finger drag. But just earlier I was holding coffee with the left hand, while using the trackpad to the right hand, and was glad I had three finger draw. I like doing "basic" mouse operations with only one hand (including right click: two fingers), and three finger drag works extremely well for me. I barely even think about it, it's automatic and an easy gesture for me.
In turn, I am interested why you do think that your way is (apparently universally) better?
Yeah, that's what I thought - you haven't used it before confidently rejecting
The other way is better mostly because it doesn't interrupt the drag when you move fingers up (e.g., when you've started drag right at the right touchpad side and don't have enough space), though there is an invisible timer hack that tries to address it, and since 3 fingers take more space on the touchpad, so you're losing range
> coffee with the left hand
Still possible with the keyboard, though loses on convenience, likely better to dedicate some area of a touchpad for a touch+move to drag
> with only one hand (including right click: two fingers),
This doesn't make sense, literal right lick is 1 finger of 1 hand, same as bottom-right corner tap
And it's not universally better, don't make it up, just better than what I've explicitly mentioned
> sometimes for example having my forearm lying in front of the keyboard.
But you can still reach space or right command key with your middle/ring finger? That would allow you to use 1 finger to drag, not worry about lifting your dragging finger while dragging and get more range
> What doesn’t make sense?
You listing that gesture as some kind of alternative while the default is already 1-handed
> I don’t see the downside either.
The downside is that scrolling with two fingers might misfire when you change your mind and cancel scrolling right away, so place 2 fingers and lift them up, thus triggering a right click
> so far I don’t see a strict ordering that applies to everyone or even every situation.
And you'll never see it with your eyes closed. You need to actually try this stuff to be able to judge it, to see whether you drink coffee often enough as a % of your computer time to make the worse gesture better because it frees up your hand and the other one-hand alternative is not as convenient, or whether the mistakes of breaking a drag gesture on a bunch of files/objects in a graphics app leaving them in the wrong place are bad enough
