How often do you use keyboard shortcuts?
I was reading @kev's recent blog post about his @frameworkcomputer, and he noted that one of the hardest parts of moving from a Mac to whatever he was using at the time was different keyboard shortcuts.
I spend a LOT of time in the terminal, but when it comes to GUI tools, Copy/Cut and Paste is really the only keyboard shortcut I use. Maybe it's still early in my day and the coffee hasn't kicked in yet, but I'm struggling to think of more.
