"1. When dragging and dropping files and/or folders between
locations in the file manager (Krusader, Konqueror, etc), there
will always be four options available to you: Move, Copy, Link, and
Cancel. Don't just point, click, click and forget about it like you
do in Windows. Be sure you know what you want to do when dragging
and dropping.
This might seem like an additional step that you shouldn't have
to take, but in reality, it's a blessing in disguise. Instead of
having to do some weird key combination in order to do something
different than the default behavior, you're given the four possible
behaviors you can perform in a menu that asks you each time you
drag a file between drives or folders."
