Answer:
A keyboard shortcut is a series of keys you can press to complete a computer command. As a common convention, keys that are meant to be pressed at the same time are joined by a + in written text. For example, Ctrl+S means you should press the Ctrl and S keys at the same time.
There are many, many keyboard shortcuts. However, you will probably only need to use a few. We will use many of these shortcuts throughout the course.
Cutting and copying can be used on files, folders, and text. Both are followed by the Paste command. So what’s the difference between cutting and copying?
The cut command removes the selected data from its original position, while the copy command creates a duplicate; in both cases the selected data is kept in a temporary storage tool called the clipboard. The data in the clipboard is later inserted in the position where the paste command is issued. The data is available to any application supporting the feature, thus allowing easy data transfer between applications.
Think of using scissors to cut out a line of text on a printed sheet of paper and pasting it onto another sheet of paper. The line is no longer part of the original piece of paper when you cut it out. Now think of using a copy machine to copy the sheet of paper. The line of text is still on the original sheet of paper.
NOTE: CTRL+ALT+DELETE
Ctrl+Alt+Delete is a useful tool for terminating crashed programs or shutting down a frozen computer. Ctrl+Alt+Delete interrupts whatever your computer is doing and allows you to shut down your computer or access the Task Manager. The Task Manager shows every program currently being used and allows you to close unresponsive programs or background tasks.
