I see and thank you for your reply; I just have one more question: If you select "desktop interaction", doesn't that by default "unselect" browser ... um ... "selection"?

In other words, when desktop is selected, how does my desktop "know" that of all the other possibly relevant things open (for example, a notes or word processing app), that it's "Oh, you probably wanted to undo what you just typed into your browser while you were on a website in edit mode"??

Is it purely a function of "undo last thing done"?

Having said that, I just noticed that "it's you again".

As a side question, do you have a tab with my submission history perma-opened?

Because I find it odd that you of all people "just happened to stumble across this" 2 minutes after I posted it.
