How Can I Get a List of Global Variables?

Questions
1

Is there a Mathematica function that returns a list of all user-defined global variables?

2

Names[“Global`*”]
That gives you the list of all definitions within Global context.

3

Here is a small modification to F. Rodriquez’s answer.

This will indicate the memory utilized by the global variables.

checkMemory[]:=Grid[Sort[({ByteCount[ToExpression[#1]],HoldForm[#1]}&)/@Names[Global`*],First[#1]>First[#2]&]]
