An example of an eclipse Ctrl+alt+down cannot be used

FYI, though this may to different from your case, which is the my experience.

Ctrl+alt+up/down doesn ' t work after disabling Hot-keys into Intel Graphics control Panel. In preferences>general>keys>binding field, I can press Ctrl and Alt (text shows "ctrl+alt+"), but pressing Arrow K EY causes nothing. (Ctrl+arrow or Alt+arrow have no problems.)
So I must a change to the screen rotation hot-key. (e.g. CTRL+ALT+NUM0) Disabling Hot-keys seems to have problem. [*]
This issue occurs on
Intel (R) HD Graphics Family
Driver version:10.18.10.3907

I don ' t have this issue on my another PC. (disabling Hot-keys is enough)
Intel (R) HD Graphics
Driver version:9.17.10.3347

[*]side Note: (Examined with Eclipse 3.7.2, Intel hot-keys (default) disabled)
In Binding field of Preferences>general>keys,
Org.eclipse.jface.bindings.keys.KeySequenceText.KeyTrapListener.handleEvent (Event) isn't invoked when ctrl+alt+ Arrow has been pressed (SWT. KeyDown). (It is invoked when Ctrl+alt+arrow has been released (SWT). KeyUp though) so Eclipse cannot work correctly. I ' m not sure the Key-down event is eaten/suppressed by Intel driver.
This is short investigation anyway.

Translation is:
On some machines our screen-rotated shortcuts and eclipse collide, some can be disabled, but some are disabled and Eclipse is still unavailable. This needs to change the screen shortcuts to avoid conflicts with eclipse, and then it's good.
