问题 This question already has an answer here: How to use Firebug's debugger functions? 1 answer I am new to FireBug Debugger can anyone say what is step into,step over and step out 回答1: Step into will cause the debugger to descend into any method calls on the current line. If there are multiple method calls, they'll be visited in order of execution; if there are no method calls, this is same as step over.

I try the following code: var myList = new Object(); var item = new Object(); item.text = "item-1"; myList[3] = item; console.log(myList); console.log(myList[3].text); // Assign another object to the same entry var item2 = new Object(); item2.text = "item-2"; myList[3] = item2; console.log(myList); console.log(myList[3].text); The result is quite odd:

问题 I can't believe that neither a Google or SO search has turned up a definitive answer or even much discussion for this, but: Is it possible to edit/customize keyboard shortcuts in the Google Chrome JavaScript debugger? if so, how? I'm used to Eclipse's F5 / F6 / F7 / F8 debugger step into/over/out of/resume keys, and want the same bindings in Google Chrome. F10 / F11 are default Expose keys for OSX and therefore not ideal for debugger control. I'm open to unorthodox solutions, e.g. Quicksilver
