I don't have an experience with any debugger in any language, but I recently found some videos showing Firebug.

I'm now playing with Firebug with a script I included an error with.

What I understand now is:

I can set a breakpoint, which is shown as a red circle.
Firebug stops at the breakpoint and gives me 4 options (Continue, Step Into, Step Over and Step Out).

What I don't understand are:

What is the difference between the 4 options (i.e., Continue, Step Into, Step Over and Step Out)? To me, Step Over is sometimes similar to Step Into... I could be wrong here.

I would be grateful if you could explain the differences of the 4 options.
