Firebug has a magic $1 variable that's available from the Console to access the inspected node. We should support this variable in the Inspector's Console.
Thats a shame that Firebug uses $1. I was considering doing the gdb $n to refer to previous console results. More people might be familiar with Firebug's concept though.

$1 isn't available in Firebug 1.2b2. I don't know if it's a bug or if they abandoned it. By the way, I've asked other web developers, nobody knew this shortcut. Maybe you could agreed with Firebug developers on a more standard way to do this.

According to this old documentation, I think $0 is the inspected node. http://www.joehewitt.com/software/firebug/docs.php
Created attachment 22794 [details] not working patch $0 seems to receive the appropriate object, but the security seems to block usage. For example, calling "$0" seems OK, but calling "$0.innerHTML" returns undefined. I tried doing wrapCallback on the node but that doesn't work either.
Maybe this could have a less obscure name, like console.selectedNode or something. With autocomplete the typing is not a big deal and it is more memorable and less likely to conflict than $0.
(In reply to comment #7) > Maybe this could have a less obscure name, like console.selectedNode or > something. Putting it on the console object may not be ideal, since it's unlikely we want web pages to have access to this variable.
Created attachment 33221 [details] Implements $0, $1, $n I've finally figured this out. JSInspectorCallbackWrapper wraps the return value with JSInspectorCallbackWrapper::wrapOutgoingValue. It wraps it as a JSInspectorCallbackWrapper, which blocks getProperty, setProperty, deleteProperty, construct, hasInstance, and getPropertyNames. I think this is overkill for objects from the "inspected window" but a necessary security measure for objects from the "inspector". $0 - Variable containing the most recently inspected object . $1 - Variable containing the next most recently inspected object . $n(n) - Returns the nth most recently inspected object that has been inspected.

> Firebug really adds a $n function? Not just $0, $1, $2, $3 and $4? Yah, documentation on this is rather hidden. Its at the bottom of Joe Hewitt's site: http://joehewitt.com/software/firebug/docs.php
Created attachment 33237 [details] Syntax fixes $n is pointless. It's only in their old outdated documentation anyway. (The assert* commands seems to have been deprecated) I vote to ditch it.
Lets ditch $n.
Created attachment 33238 [details] No more $n
