Are there programs (applications) that you regularly use that aren’t in your dock and what is the dock anyway?
The dock is much like the desktop in Windows. It provide shortcuts to your most used programs (applications). When you first get a Mac, the Dock comes with a default set of shortcuts, but it is likely some of your favorite applications aren’t included.
When you open an application, you will notice that its icon will appear in the Dock. However, the icon will disappear when you quit the application.
To permanently add applications to your Dock, follow these easy steps:
1) Open the Application that you would like to add to the Dock.
3) Right-click and then put your cursor over Options.
4) Click on Keep in Dock.
The icon will permanently live in the dock (unless you remove it) and will provide a quick and easy way to open your favorite applications!
