  26. Windows Because “Welcome to Files” Didn’t Have the Right Ring to It.

  27. A Brief Detour on Mousing Left Click (Click) – refers to pressing and releasing the left mouse button. This command is used to select files and icons and move cursors. Since this is the most common button used, it is often referred to as just “Click” or “Clicking.” Double Click (Click-Click) - refers to pressing and releasing the left mouse button twice in rapid succession. This command is often used to open folders and documents and to run programs. Right Click - refers to pressing and releasing the right mouse button. This command is often used to bring up a list of frequently used commands within a given program or to display the properties of a selected item.

  28. A Brief Detour on Mousing Click and Drag - refers to pressing and holding the left mouse button and then moving the mouse. This command is most often used to move icons or files around or to help select multiple files or icons. Scroll – the process of displaying more information in a window by moving the contents of the window up and down. This can be achieved by either using the scroll wheel on the mouse or using the “scroll bar” on the selected window. Mouse Over – the process in which the mouse cursor is moved over an item, such as a button or icon, and held in place for a brief moment to display identifying information about the item.
