Is there a way to list all the user-defined variables & function in a Notebook ?
I would like this for the comfort it brings to a notebook overview as well as to spot potential multiple use of a variable name (thus redefining it accidental)

To find names in a context, say in the Global context, try
Names["Global`*"] --Nasser

More straightforward:
Names[$Context<>"*"].

& Alexey, Thank You ! Would you think about a way to list separately the Function, Variable or options used ? Many Thanks.

@500, I do not know how to find if it is a function you defined, but for build in function, this is how I do it isFunction[name_String]:=Module[{m}, If[Length[SyntaxInformation[Symbol[name]]]>0,True,False]]; for example: isFunction["Plot"] will return True. this works only for functions which have synatxInformation.

Is
Names[$Context<>"*"] more straightforward because it gives the current context instead of assuming that the current context is Global?If you want a friendly interface to pop up, try the standard information printing character ? or ??
You can apply it to the global namespace as:
?Global`*
