Paint bucket, smudge and other tools missing

Sorry If I am completely stupid, but the last version I used was 3.0

Ok big problem I am so frusrated I can barely sit here anymore. I am looking at all my tools on the left hand side. I get to the tools by going to window-> tools out of all the tools, there is no smudge or paint bucket. who knows how many other tools are missing. so i went to help and find and typed in smudge and paint bucket and nothing.
I googled cs4 paint bucket and smudge and apparently there is such options for cs4. but there are NO icons in the tools. what do i do???

The Paint Bucket shares a box with the Gradient tool (shortcut = G); and the Smudge tool shares a box with the Blur & Sharpen tools.

Oh i see, I hold down option and click it and it changes. Wow thank you soooo much! I have no clue why they didn't put that in help. Thanks!!!
