I would normally agree with you here except that I've accidentally renamed files on Windows so many times only to lose them because something was in focus that I didn't intend to be. I use a combination of the mouse and keyboard when browsing and the fact that I can accidentally click on a file (which renames my current file to that file) and save or click enter thinking that I'm saving which then just starts to rename the file is utter garbage in an Open or Save dialog box. I feel like the only things I should be able to do are Open a file or Save a file but not rename other files. Neither is a good solution so it comes down to preference but I definitely see the reason for it because it happens to me on Windows all the time.
