To prevent closing Firefox and other application by a mistaken Ctrl+Q I added a keyboard shortcut with this combination witch opens xclock.It works fine but unexpectedly the shortcut Ctrl+A ==> Select all doesn't work any more system wide.Why the universal shortcut Ctrl+A is implicitly affected by the create of the shortcut Ctrl+Q?How to prevent this?
