I recently thanked Tobias Rittweiler for his work on slime inspector and suggested some usability improvements for it in his blog: http://trittweiler.blogspot.com/2009/05/slime-tidbits-2009-05-14.html?showCo...

As it was requested, I re-post this comment here.

It would be very nice if you add some simple key binding which lets user immediately edit the slot corresponding to the line the cursor is in. As a user, and I think I am very much like many others, most of the time I edit just one slot. Only then I look at the next, decide whether I should edit it, and what value to bind it to. It is very uncomfortable to mark it first, then move to the bottom of the list, push "Set value" and only then enter a new value, or values, which I must stack in my memory first. There should be easier way, like one-key combination.

Also your solution needs some key to unmark all marked slots.

Thanks for your great work!
