Comment 19 for bug 48671

So essentially there's "accidents" with both methods. With the traditional F2 shortcut there's the F1 and F3 accident (never done that myself), and with the click to rename there's the accidental entering rename mode (which happens frequently enough to me that I've actually noticed and am making an effort to share my opinion here).

I'd say your post, agro, validates my suggestion of having the default as "click to rename" (btw, do you use icon or list view by default?) as the default behaviour, but having the option to disable it for the veteran GNOME users. Though really, there's always Kubuntu for those who like "The Windows Way" :)
