This may be 90% cargo culting, 10% reality. One of my former co-workers desperately wanted to be perceived as an Excel ninja, and had heard that people who had achieved guru-level Excel mastery would remove their F1 keys, and so one day pried off her F1 key. Meanwhile the person in our office who probably could have written Minecraft in Excel and then built an Excel simulator in Excel Minecraft had a keyboard with a conspicuously intact F1 key.
Same thing happens in programming circles. I am not exempt: All my MacBook keyboards get their caps lock keys remapped to control, in honor of my Apple II childhood and SunOS pizza box college heritage.
