Re: [Trisquel-users] There is a mysterious "erase my work" key somewhere ...

Are you pressing Ctrl+Right? That switches the workspace to the right. This  
doesn't close anything, but it would render all windows invisible.

I honestly don't get why, but Trisquel's default setup gives you multiple  
workspaces without any workspace switcher applet on the panel. You can add  
one from the panel's right-click menu (and then move it by holding Alt and  
right-clicking on it).
