Mathematica Tutorial: Notebooks And Documents - Wolfram Research

144 Notebooks and DocumentsWhen you define a function f , you can usually display its value using ? f . However, if you give ausage message for f , then ? f just gives the usage message. Only when you type ?? f do youget all the details about f , including its actual definition.If you ask for information using ? about just one function, Mathematica will print out the completeusage messages for the function. If you ask for information on several functions at thesame time, however, Mathematica will give the name of each function, if possible with a link toits usage information.In[6]:=This gives all the symbols in Mathematica that start with "Plot".?

However, if you use Mathematica with anotebook interface, then you will be able to give much more extensive documentation in textcells in the notebook.
