I’m a working with eclipse in Ubuntu. In eclipse, i frequently use a shortcut “Ctrl + Alt + Down Arrow” to duplicate the current line. I found that Ubuntu also has the same shortcut to switch the workspaces. So, my problem is when I press “Ctrl + Alt + Down Arrow”, it calls the system’s action. I tried this by disabling the keyboard shortcut in Ubuntu too. Still, it didn’t work for me. Can anyone help me on this problem ?
1st solution: Remapping binding in eclipse
Have you tried remapping the binding in the preferences?
Window -> Preferences -> General -> Keys
Type “copy lines” in the filter.
Select the entry and edit the binding – I changed it to Ctrl+Alt+Numpad_4 and this seemed to work.
2nd solution: Disable keystroke in compiz
Note my actual fix for this is to disable a setting in compiz, but yo said this failed, here’s what I did anyway in case it is useful:
System->Preferences-> ConpizConfigSettingsManager
Click “Advanced Search”
Type “down” in the filter box.
Click on “Desktop wall”
Disable “Move Down”.
