Thank-you boydner, it worked on a Word document, so I suppose it would work generally.
What I used was fn-option + left arrow for the top of the document, and fn-option + right arrow for the bottom of the document. This is a bit counter-intuitive, ie not using the up and down arrows, but if it works, fine.
You're welcome! It was a keyboard shortcut I used frequently before I bought my Air so it was really annoying not being able to use it. I finally figured it out soon after reading this thread and thought others might like to know.
The fn-Option + up arrow worked to move to the top of a document for me but the fn-Option - arrow does not work to move to the end of a document. It was counter-intuitive to use fn-Option + right arrow key to move to the end of the document. I hadn't tried fn-Option + left arrow yet so thank you for that information. I'm just happy to have a shortcut for this function again!
I have a Macbook Air Nov 2012 with OSX 10.8
cmd + left arrow: Go to beginning of the line
cmd + right arrow: Go to the end of the line
cmd + up: Go to the beginning of the document
cmd + down: Go to the end of the document
HOWEVER in Firefox...
The above commands do completely different things.
And instead, to go to the start or end of a line I use
alt + left, or alt + right.
This is all kind of infuriating, and after a week I miss my 17" Dell monster.
This MBA just feels like a glorified point-and-click machine for browsing.
I wish there was a premium PC laptop built with the same aesthetics!
I hear you brother!! I only bought this blasted thing (13" MacBook Air Mid-2013) for its aesthetics, SSD and battery life...was running Windows exclusively on it until recently when I was forced by my uni tutors to install OS X. Windows + MacBook Air = best user experience a Windows lover could ever ask for! But Mac OS X + any hardware = going bald from tearing out your hair in frustration! Unless of course you grew up with Macs...then I imagine Windows + any hardware = going bald from tearing out your hair in frustration! I guess you gotta take the good with the bad
