What can I do with this if I do not have a mouse?

Probably most of you have noticed this inconvenience. In a situation like this:



If I want to choose Cancel, I have to click the Cancel button with my mouse/trackpad.

I am a big fan of always keeping my hands on the keyboard and I am wondering if there's a way to move the highlight onto the Cancel button without using the mouse?

In this special case above, I know I can press ESC for the cancel button. But there are times when the highlight is on the Cancel button and I want to press OK, without using my mouse:



Thanks a lot

 

I think press (table)

 

press tab until the button you desire is highlighted, then spacebar.

 

That's what first comes to my mind, because that's how I do it in Windows.

But the Tab Key just doesn't work for this under OS X.

 

Finally, I found the solution to this problem

In order for the Tab key to work in this situation:
System Preferences-> Keyboard&Mouse ->Keyboard Shortcuts
select 'All controls' at the bottom

After this, tab key+spacebar will work
