Tabbing between options

I am a new mac user and can't seem to find an answer to this.

When you get a pop up say in safari asking you if you wish to save a login you have 3 options not for this website, not now or yes. How do you tab between the options via the keyboard instead of using the mouse,pad?

You use tab in windows but it doesn't work on mac and I can't seem to find an answer, is it possible?

System Prefs >>> Keyboard & Mouse >>> click the Keyboard Shortcuts tab.

At the bottom of the window Check the "All Controls".

....

When using it... you press the space bar to "click" a button with a blue CIRCLE around it... you press ENTER to "click" the Blue SHADED button.

That is great thanks for the clear explanation, however is it not possible to select the middle option "Not NOw" from the keyboard?

Click to expand...

pressing tab will move the "blue border" around to the different controls

press enter to select the default option (the one completely shaded)
press spacebar to select the one with the blue border

Brilliant, thanks!
