I started using Boot Camp to run a Windows environment for development/server management at my IT job. However, I quickly ran into a huge annoyance. I didn't realize until the switch how often I used ⌘+left/⌘+right to quickly jump to the beginning/end of a line of code. This is no problem on a Windows machine, as their keyboards have a Home and an End key for that exact purpose. However, there is no Home/End key on a MacBook! If you have encountered this problem then you might understand my frustration.
Fret no more! On a MacBook Pro running Windows in Bootcamp you can jump to the beginning or the end of a line by using the Function key.
fn+left/right is what you are looking for.
