I use 2 methods, neither as easy as hitting "Talk" on an un-submitted page.
- Add Personal Nodelet to your sidebar. The "add" links include the node_id in the URL, you can copy the link, paste it in the address bar, and delete the options after "...node_id=1234". BTW, if you don't like the links stacking up in the Personal Nodelet, you can hit "Collapse List" in user settings.
- Create a "Custom Node Title Definition" in user settings. I use "%T [%N] %S" to generate a node title (in the browser title bar) which looks like this: "Re: Refreshing the Current Node  note". Just as you suspect, that number is the node id; type that number into the address bar, with the appropriate URL sugar.
Definitely not a mindless clicking exercise, but those 2 tricks save a bit of time.
