I am not familiar with debugger(). I only showed how to list all function definitions in a group of files.

Great help! Thanks a lot! The only problem is how do I escape from a big loop? Lets say after a few iterations in that big loop, I've already got enough of the loop and wanted to escape the loop and debug the next line after the loop...? Thanks again!

Thanks a lot! How do I iteratively loop your function thru all scripts under a big folder and its sub-folders? Thanks again!
