• h get help
• l list the code where you are
• reload if debugger doesn't pick up changes in your code give it a little kick
• cont carry on execution

That should be enough to keep me happy

Rails has a number of helpers which put fairly chunky bits of javascript into your html. This isn't the purest solution, and is particularly messy for accessibility when javascript is disabled. A number of people have addressed this issue which I'll discuss here
