Hi guys, I got my first mac last month. It's a new macbook and pre-installed leopard. I'm sure loving my macbook and Mac OS X leopard as well. Some questions I have. As I'm new mac user so kindly remove my problems I'm having: 1. Tell me, is there any keyboard shortcut to delete a file or folder at once and permanently without moving to trash. ( In windows, there is keyboard shortcut, Shift+del) 2. Is there any option to lock (password) a file or folder in Leopard? if not then tell me any good software. 3. The main problem i am having is about uninstalling 3rd softwares. I read to uninstall software we just have to delete them, thats it. Is it correct or is there any other way to completely remove a software. Recent I have install a software called graphics converter, later I delete it. But when right click on any file, folder or desktop, it still gives graphics converter options. So, how can i remove those option from right click menu?
