View Source for Predefined Blueprint Nodes

I dug through the source for a bit to try to find the definition of the “Exit” Blueprint node but wasn’t able to find it.
Would someone be so kind as to show me the best way to find the source for existing Blueprint nodes?
Is there a shortcut I don’t know?

got it! it’s “Go to Code Definition.”

Right click the node and view source. Or view code. Something like that. If it’s a c++ node, it will go to the source. If it’s a bp defined function, double clicking the node will take you to the bp source.

I only get Reading C++ Symbols. Nothing is shown!
