Perhaps you could use the ? option.

For example you want to find out what are the paramters for
CholeskyDecomposition.  Simply type:

? CholeskyDecomposition <shift+enter>

and it returns

CholeskyDecomposition[m] gives the Cholesky decomposition of a matrix
m.  More...

Click on more and it goes to the help.

You can also do "? MyFunction" if you have already declared a function.

For example if you create MyFunction as

MyFunction[Avar_, Bvar_, Cvar] := Avar*Bvar/Cvar

and then type

? MyFunction

It will return

MyFunction
[Avar_, Bvar_, Cvar] := Avar*Bvar/Cvar
