Need help with the tab key

[Watabou]

Here's a dumb question but its really annoying me right now.

I know in Windows you can tab over a button and then hit Enter to confirm. But is there any way I can do it in Mac OS X?
When I hit tab, it only outlines the "add" button shown in the attachment. Is there any way to move the whole selection over with the tab key? Or is there any other keyboard shortcut?
It would seriously speed up my work right now. I exported a lot of pictures from my psp and it comes up as Unix executable file for some reason and for the preview, it has a really small picture. When I add the .jpg extension, it becomes normal and a large picture again.
Here's is what I mean. I need the whole selection from "'dont add" to "add":

I don't think you can do this in the Finder. In some applications, you can press the first letter of the button you want to press, or press CMD and the letter, but that doesn't seem to work in the finder.

In Safari, there is an option to allow you to tab to each field/control on the page, but I couldn't find anything that would work in the Finder for the example you are looking for...

Anyone?

Don't bump your own thread, If people want to answer it they will, if they don't , they won't.

Bumping just annoys the people who would normally answer your question, but now won't.

You can "push" the outlined button by pressing <space>.

Finder >> Preferences... >> Advanced >> uncheck "Show Warning Before Changing Extension

and if you want to change so many names at once just make an Automator script. It's a very useful application.

Thanks! I didn't know I could do that. I don't know about Automator though. I would like to give it a try but for most of the work I do, I don't need it.

Oh and thanks ergdegdeg, I was trying out everything like pressing control+tab and even Fn+Tab except space lol. It works now.
