Comment 3 for bug 1196164

"The current bindings work great on FOSS desktops with FOSS applications that are designed specially for this environment. But what about big, multiplatform applications? What about appliations that we expect to be multiplatform some day?"

If it already works "great", but there is an issue with external "big" applications, then the bug belongs with the external applications, not with Unity.

Super does OS-level actions. Alt does window-level actions. Ctrl is available to the application. That is the consistency. Note that Locking the Screen has recently been changed to Super+l to support this consistency. But changing Alt breaks this consistency.
