I have a row of macro keys on my keyboard on the left side. I thought I’d be smart and add copy and paste macros (that were near mm’s away from Ctrl) and I never used them.
Muscle memory would always take over and I’d Ctrl+C Ctrl+V. I realized it would take more work to train myself to use the macro keys (and God forbid I used a different keyboard) than I was saving not having to press a key combination
It was more than just the phone books. Back before smart phones, if you needed to look up a phone number you’d call information (411) and they’d look it up for you. For instance, if you were stuck on the side of the road and needed a tow truck.
Information would be able to look up businesses close to where you were using the NPA/NXX of the phone number you were calling from (the first six digits of the number including the area code) and then give you a couple options in alphabetical order.
I had a client who had a phone number in every exchange in NYC and had a name like “AAA Towing” so no matter where in NYC you called information for a tow truck from, they’d usually be the first option given to you.
