1. I've been using home/end extensively for decades. I had a Windows computer since early 90s and started learning to code on notepad so I never learned ctrl-a/e until later on, so I stuck with home/end. In modern days work laptops are alwasy Macs so in fact I've had to map home/end to work like it does on Windows (go to beginning and end of line). 2. Similarly since I now use a Mac more often than Windows, I just map Caps Lock to Esc. This has been particularly important due to the Esc key having been moved to the touchbar. I've gotten very used to reaching for the location of the Caps Lock key when I need to press Esc. 3. I do use space bars with both hands.
