A little known feature in SMIT when selecting software to install is the ability to scroll over to the right using the right arrow key to view the actual fileset name rather than just the fileset description. This makes it easier to verify that you are installing the desired fileset.
I had been using AIX for many years before I found this feature. I think it is not very commonly known because even if you have a large terminal window the software selection screen is always the same small size and doesn't ever show this information unless you scroll over with the right arrow key. The message says "Use arrow keys to scroll" but I had always thought you could only scroll up/down in the list.
Here is an animated GIF image that visually shows what I'm talking about (the image is large so it might take a minute to download in your web browser):
