Summary: Alt + Left Click to move windows has a tendency to conflict with creative workflow apps. While Alt can be changed to Meta in KWin's settings, Alt + Left Click shortcuts often cannot be customized in apps. Rather than making every user who runs into this problem change their settings, we should change our default settings to improve KWin's default usability. The fact that Alt + Left Click to move windows is older does not matter. We are trying to use Meta for global/shell shortcuts anyway.
BUG: 399375
Test Plan: The relevant parts of the relevant tests pass. kwin-testInternalWindow fails, but for unrelated reasons that have something to do with XWayland.
Summary:
e.g. "Vertically maximize" is more natural and expressive than "Maximize (vertical only)"
See D29671#inline-169882.
Test Plan: New strings appear in the KCM
