Content:  The Shift key is a modifier key on a keyboard, used to type capital letters and other alternate "upper" characters. There are typically two shift keys, on the left and right sides of the row below the home row. The Shift key's name originated from the typewriter, where one had to press and hold the button to shift up the case stamp to change to capital letters; the shift key was first used in the Remington No. 2 Type-Writer of 1878; the No. 1 model was capital-only. On the US layout and similar keyboard layouts, characters that typically require the use of the shift key include the parentheses, the question mark, the exclamation point, and the colon. When the caps lock key is engaged, the shift key may be used to type lowercase letters on many operating systems, though not on macOS.
Title: Control-C
Content:  Control+C is a common computer command. It is generated by pressing the key while holding down the  key on most computer keyboards. In graphical user interface environments that use the control key to control the active program, control+C is often used to copy highlighted text to the clipboard. In many command-line interface environments, control+C is used to abort the current task and regain user control. It is a special sequence that causes the operating system to send a signal to the active program. Usually the signal causes it to end, but the program may "catch" it and do something else, typically returning control to the user.

Title: Shift Out and Shift In characters
Content:  Shift Out (SO) and Shift In (SI) are ASCII control characters 14 and 15, respectively (0x0E and 0x0F). These are sometimes also called "Control-N" and "Control-O". The original meaning of those characters provided a way to shift a coloured ribbon, split longitudinally usually with red and black, up and down to the other colour in an electro-mechanical typewriter or teleprinter, such as the Teletype Model 38, to automate the same function of manual typewriters. Black was the conventional ambient default colour and so was shifted "in" or "out" with the other colour on the ribbon. Later advancements in technology instigated use of this function for switching to a different font or character set and back. This was used, for instance, in the Russian character set known as KOI7-switched, where SO starts printing Russian letters, and SI starts printing Latin letters again. Similarly, they are used for
