It's tangential to the article, but I've found it's been really helpful to have dedicated copy and paste buttons on the left hand. On Linux the highlight and middle click is nice, but not every application can be selected (like split windows in tmux) and the buffers don't always match between applications (like Firefox and something else). But I've found Ctrl+Insert and Shift+Insert works practically without fail everywhere. I have a programmable keyboard so made macros for those two commands and mapped them to keys on the non-mouse hand (extra thumb keys on an ergodox, not bad to lift the hand a little to reach them). Works great! For something so universal as copying text it would make sense to have dedicated keys for them on many keyboards, like volume up or down.
