>One of the things I find quite difficult to mentally adapt to when switching is the behaviour of the Enter key, since in Windows it is open, and in OS X it is rename (which I find much more useful, since you can command-down arrow to open which is used for folder navigation with command-up for opening the parent folder). For future reference, you can rename in Windows/Linux using F2. Works in Windows Explorer, and in most Linux file browsers that I have tried, though who could ever claim to have used them all? ;) As for [Modifier]+Down to enter a folder, that makes a lot of sense and I like it. The last time I used a Windows machine (Win7 I think), I noticed that they had finally adopted Alt+Arrow navigation in Explorer. Alt+Up goes to the parent folder, same as Linux (and OS X it seems!), and Alt+Left/Right goes backward/forward in folder history. I'll probably try and add Alt+Down to one of my Linux file managers sometime, because it makes much more sense than having to switch to Enter for going into something, and Alt+Up to go back out.
