Do yall use your mouse with your left hand and then switch up keybinds, or use mouse wiht right which i feel like would put you at a disadvantage with people that are rigth handed having more minute control over small movements.
The lack of left handed mice taking off should tell ya all you need to know (best we got is ambidextrous and even those are rare and generally cheap/ergonomic office mice)
You wont learn it from your parents (since no one puts any thought into stuff like that) and youll have to constantly swap the position of keyboard + mouse during the learning process since youll be sharing a pc with a right handed parent
And just too inconvenient to swap nowerdays
Its sorta like how writing was in the past (less violent, but the idea of it). You just had to write with your right hand, who cares if its your dominant one.
So while I do all my activities with my left per default, you were expected to write with your right and thats not worth relearning after youre done with school (/the years teachers stopped giving a shit)
