Hi, I have a CentOS 7 (GNOME) desktop installed as a VirtualBox guest on my Slackware64 14.1 workstation, to fiddle with it. Guest Additions are installed and configured OK, and 3D acceleration is working too. In its default configuration, the GNOME desktop under CentOS shows an "exposé" (I don't know how you call this), a list of all open windows, when you move the mouse cursor to the upper left corner of the screen. When no window is open, you just see the sidebar with the application launchers, and on the right side you see the empty virtual desktops. Is there a keyboard shortcut for this mouse gesture? I'm asking because on my dual-monitor workstation, the CentOS guest is displayed full-screen on my right monitor, and the mouse gesture seems to be ineffective.
