If we compare MessageName in 5.2 vs 6, we see that the notes are identical, but 6 includes several examples involving MessageName which 5.2 does not. Also, for looking up specific function help, I don't think 5.2 and 6 are that different. In both 5.2 and 6 we can do ?:: and then click on the link to get the MessageName help. Also, in both 5.2 and 6, if you type MessageName in the notebook, put the mouse pointer inside the word and then click find selected function, you will go directly to the MessageName page. I think the only place where 5.2 is different, and more convenient for finding help on a specific function, is when one looks up a function after opening the help browser. In this case the lookup field is selected and blank. Moreover, as you type different entries in an hierarchical table of contents are highlighted. In my usage of Mathematica, I usually know which function I want to use, and I'll type it into the notebook. At that point, sometimes I'm not sure about an aspect of using that function, so I'll move the mouse pointer to the function and hit 'Find selected function', bringing up the help for that function, which in general is very complete and useful. Consequently, for me the help in 6 is much better than in 5.2 as the function page documentation is better. Are there other issues related to finding help for a specific function that make 6 worse than 5.2? Carl Woll Wolfram Research
