Reading through the comments here, it’s amusing to see how many people make assumptions about how things should be just because that’s how they work.

Someone above claimed that not being able to blind type function keys shows severe keyboard incompetence, something all trained computer typists should be able to do.

Well what about us poor souls who are trained mechanical typewriter typists? We didn’t have function keys?

The age discrimination is real!

This works pretty great, especially since eg. ctrl + backspace (I don't know about Macs, does cmd + backspace work?) deletes the entire last word.

Without remapping the capslock you need both hands to execute this shortcut, which makes it much less practical.

It's very useful to switch input layouts.
