Some important functions performed by some of the keys are:
              •  Control Keys: These keys such as Control (CTRL),  SHIFT, SPACEBAR, ALT, CAPS LOCK and  TAB are  used in
                combination  with  other  keys to  perform  specific functions  related  to  the  operating  system or  software
                applications.
              •  Enter Key: The Enter key, also known as the Return key, is a fundamental key on a computer keyboard. Its
                primary purpose is to execute a command or to move the cursor to the next line in a text document.
              •  Punctuation Keys: The Punctuation keys include keys for punctuation marks, such as colon (:), semicolon (;),
                question mark (?), single quotation marks (‘ ’), and double quotation marks (“ ”) are essential for proper grammar,
                syntax, and communication in written language.
              •  Navigation Keys: These keys allows you to move the cursor or navigate through text and documents. They are
                essential for editing, selecting, and moving within different software applications. Arrow Keys (Up, Down, Left,
                Right) allows you to move the cursor or highlight text in the corresponding direction. The Home key moves the
                cursor to the beginning of a line of text or at the starting of a document. The End key moves the cursor to the
                end of a line of text or at the end of a document. The Page Up key scrolls up one page at a time in a document
                or on a webpage. The Page Down key scrolls down one page at a time in a document or on a webpage.
              •  Command  Keys: Command keys, such as INSERT (INS), DELETE (DEL),  and BACKSPACE, execute specific
                commands or functions within an application or the operating system.. When the INSERT key is turned ON, it
                helps you overwrite characters to the right of the cursor. The DELETE key and the BACKSPACE key are used to
                remove typed text, characters and other objects on the right and left side of the cursor respectively.
              •  Windows Key: It is often denoted by the Windows logo (  ), and is found on Windows-compatible keyboards.
                Pressing this key opens the Start menu.

                       Mouse Operations in Windows 11


              Mouse is an important input device in a graphical user environment like Windows where the user has to do simple
              mouse clicks to get the job done. Windows 11 is designed to make the mouse easier to use. Let us now see how
              useful this pointing device is in Windows 11.
              •  Single-click: This is the most common task performed by a mouse in Windows 11. We can select a program, file,
                folder, menu, sub-menu, option, etc. using a single left mouse click. Whichever option is to be selected, move
                the mouse pointer to point to that area and do a single left mouse click to select that option.
              •  Double-click: When we use the left button to click twice in quick succession, then, it is called a double click. We
                generally use double click to open a file/folder, to open a specific program or application software.
              •  Right-click: To display context based pop-up menu or shortcut menu, we use the right mouse button click. For
                example right clicking on a cell in a spreadsheet gives you important formatting features of the cell.
              •  Drag and Drop: Drag and Drop is used to shift the location of a file, folder or a program. We select an object
                and press the left button down. Without releasing the mouse button, drag the object to a new location and
                release the mouse button to drop it onto a new location.
              •  Hovering: Hovering  means moving the cursor  over  an option or  an object without  clicking it. This action
                can trigger certain responses from the operating system or software applications, such as displaying tooltips,
                changing the cursor shape, or highlighting the element.

                       Performing Basic File Operations


              In a school or office, each teacher has a dedicated cabinet where they organise files for different students or
              classes on  individual shelves.  Similarly, a  computer  stores  information  in  electronic  files, which  are  organised
              into separate folders. Managing these electronic files is much easier, as they can be effortlessly copied, moved,
              renamed, or deleted.
