title: Undo shortcut not working in Eclipse
body: <p>The last couple of days the <kbd>Ctrl</kbd>+<kbd>Z</kbd> shortcut (Undo) scrolls down a line (a-la emacs). I tried to switch schemes back and forth, change and redefine the Undo in Default scheme, nothing seems to work. Other combinations (<kbd>Alt</kbd>+<kbd>Ctrl</kbd>+<kbd>Z</kbd>) work fine, other workspaces work fine with <kbd>Ctrl</kbd>+<kbd>Z</kbd>.</p>
  
  <p>Any tip that will save me from redefining the workspace?</p>
