Here's an existing tip o' the day: "Ctrl-Shift-J shortcut joins two lines
into one and removes unnecessary space to match your code style."

I just realized that it's even smarter than that. If you have this code:

String up;
up = "down";

and you select the two lines (or just the first line) and hit ctrl-shift-J,
you'll get:

String up = "down";

I'd like to request that the join lines feature gets more documentation in
the tip and in the general help, so I can find out if it does even more
