macos - Fn + Right Arrow on MacBook Pro does not work as END Key for SuperUser web site

I am using a MacBook Pro running Mac OS X 10.5. I am new to this development environment, and previously worked on Windows.

I have tried that Fn + Right arrow on Mac works as "END" key on Windows -- which makes cursor move to the end of line, for most application like Word for Mac -- I have tried it works. But I tried Fn + Right Arrow does not work for current question input box of SuperUser. I am wondering how to solve this issue and why? Does anyone have the same issue for me?

Thanks in advance.

Answer

It's different on Mac. Generally, End (and fn-Right) will scroll to the bottom of the page. To go to the end of the line, use Command-Right.

If there are exceptions like Word, it's because they deliberately change the key behavior.
