Gnome have a lot of system-wide keyboard shortcuts that have conflict withs application-wide keyboard shortcuts.
Windows avoids such conflicts by using a dedicated key (super/window/OS key). For example in Ubuntu Alt+Shift+Up has a conflict with "move up line" in phpStorm. (Linux shortcuts have precedence to application-wide key, and I can not disable some of them.)
How can I disable all Gnome keyboard shortcuts?
Is there any app to map Gnome keyboard shortcuts to super key (or perfectly map to Windows equivalent keys)?
Essentially, why do Linux developers not use the super-key as an modifier key for OS-wide actions?
