My default operating system is openSUSE. I was searching for the keyboard shortcut but could not find one. The shortcut I was finding was the caomputer main menu. By pressing which key can I open the computer main menu. Currently the super or the key with the windows logo on it is set to open this menu. I want to disable this but the problem is that I do not know how to disable the key and from where. Does any one know about it? Please help. thanks in advance.
