Hiding while loading an app!
A great tip submitted by Zaid: Hiding while loading an app! One of the things that I already knew is that you can hide an application while switching to another one by holding down "Option" and clicking on the other one. In the same way, you can hold down "Command-Option" and it will hide all running applications except the one you are switching to. What is new to me however, is that you can use the same tip when loading an application from the Dock: hold down either "Option" or "Command-Option" while clicking on the icon in the Dock. Thanks for the great tip Zaid!
