Comment 16 for bug 431073

I completely disagree with current behavior, where spacebar does nothing, here is reasons:
1) Like Omer Akram said, pressing selected buttons is much like opening selected files, so this behavior is consistent through different UI elements

2) As for me, opening files/folder with spacebar is most efficient way of performing file navigaton, where right hand is used to select elements with mouse or arrow keys and left hands used to press Ctrl, Alt, Shift, Spacebar and number keys to:
1) navigate between tabs (Alt+#, Ctrl+T)
2) hold selection modifying keys like Ctrl or Shift
3) press copy/paste hotkeys (Ctrl+C, Ctrl+X, Ctrl+V)
4) open selected files
All that action can be performed without moving hand away.

In situation where spacebar does nothing i'm forced to constantly move left palm between Ctrl-Alt-Shift area and Enter key, or constantly put right hand off mouse/arrow keys to press Enter on NumPad, which is rally annoying. Hope at least we can get a choice in gconf or somewhere else.
