That pretty much says it.
If I accept DTP’s remarkably accurate suggestions for classifying articles, then I can just keep the cursor over the “Move to” button and hit the click button on my trackpad (MacBookPro). However, each time I need to choose something other than the recommended folder, I have to move the cursor off the button.
Since “Move to” is a default-yes kind of button, the kind that are highlighted in text dialogs, why could it not be activated by hitting return?
