I would like to make a request for the debugger.
In Microsoft Visual Studio if you right click on a
line where you are debugging, one of the options is
Run to Cursor (your F4).
This is so completely obvious and completely natural
that I find myself doing it all the time.
Each time I am reminded that it doesn't work in Netbeans,
so I click on the line and run up to the menu bar to
press on the button.
The Microsoft idea is just so great that you must incorporate it.
I'm already at exactly the line I want the debugger to stop at.
It is so natural to do a right click and pull the option.
