I use the Function keys all the time while developing - mostly for debugging.
In IntelliJ, Visual Studio (through Parallels) and Chrome, the Function keys allow me to step through the debugger. It's pretty standard in my day to day workflow, and they all pretty much use the same keys.
Esc is pretty useful in vim and it's used frequently in Windows. I could remap a key, I just don't like being dependent on custom layouts since I sometimes have to switch between machines and I'd rather it be as consistent as possible.
