How to replicate the hover in Admin Posts section?

Hi there, I am trying to figure out how word press does the hover effect to precisely when I move the mouse over the list of article names.

I am specifically referring to the to ‘Edit | Quick Edit | Delete | View’ that pops up when you mouse over or ‘hover’ over the row which contains the article name.

I did this feature with jQuery, but the div layer I am showing sticks around when you move the mouse out a certain way, or too quickly.

I am starting to believe that all I need to do is to setInterval and check the hover state, because it seems that’s what necessary, and that’s what’s done in your custom hover.js. BTW, it took a while just to find the references to that file. Reversing javascript is virtually impossible, and I still cant find the function which is called when the hover over appears, even though I put alerts in many places.

But I would appreciate any input you have on javascript debuggers, javascript development, and what tools you use at word press to help trace what function calls are being executed, and of course how I should go about replicating this hover effect. I know about Venkman JS debugger, but I really want to know how you guys develop your JS software.

Thanks for your time.
