The shift key⇧ Shift 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.^[1]

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.

Whenever the caps lock key gets engaged, the shift keys may be used to type lowercase letters on many operating systems, but not on macOS.

Labeling[edit]

The keyboard symbol for the Shift key (which is called Level 2 Select key in the international standard series ISO/IEC 9995) is given in ISO/IEC 9995-7 as symbol 1, and in ISO 7000 “Graphical symbols for use on equipment” as a directional variant of the symbol ISO-7000-251. In Unicode 6.1, the character approximating this symbol best is U+21E7 upwards white arrow (⇧).^[2] This symbol is commonly used to denote the Shift key on modern keyboards (especially on non-US layouts and on the Apple Keyboard), sometimes in combination with the word “shift” or its translation in the local language. This symbol also is used in texts to denote the shift key.

Uses on computer keyboards[edit]

On computer keyboards, as opposed to typewriter keyboards, the shift key can have many more uses:

• It is sometimes used to modify the function keys. Modern Microsoft Windows keyboards typically have only 12 function keys; Shift+F1 must be used to type F13, Shift+F2 for F14, etc.
• It can modify various control and alt keys. For example, if Alt-Tab is used to cycle through open windows, Shift-Alt-Tab cycles in the reverse order.
• In most graphical systems using a mouse and keyboard, the shift key can be used to select a range. For example, if a file is selected in a list, shift-clicking on a file further down the list will select the files clicked on plus the ones inbetween. Similarly, when editing text a shift-click will select the text between the click point and the text cursor.
• The shift key can be used in conjunction with the arrow keys to select text.
• Holding shift while drawing with the mouse in graphics programs generally confines the shape to a straight line, usually vertically or horizontally, or to draw squares and circles using the rectangle and ellipse tools, respectively.
• The shift key can also be used to modify the mouse behavior on a computer. For example, holding shift while clicking on a link in a web browser might cause the page to open in a new window, or to be downloaded.
• In some web browsers, holding shift while scrolling will scan through previously viewed web pages.
• In mostly Pinyin Input Method, Shift key usually use to switch between Chinese and lowercase English.
• In older versions of macOS (10.12 Sierra and below), holding shift while performing certain actions, such as minimising a window or enabling/disabling Dashboard or Mission Control, makes the animation occur in slow motion. For some animations, holding control will make the animation move just slightly slower, and holding control+shift will result in an extremely slow motion animation.

On some keyboards, if both shift keys are held down simultaneously only some letters can be typed. For example, on the Dell keyboard Model RT7D20 only 16 letters can be typed. This phenomenon is known as 'masking' and is a fundamental limitation of the way the keyboard electronics are designed.^[3]

Windows specific[edit]

The following is a list of actions involving the shift key for the Microsoft Windows operating system.

Some functions (like Sine and Cosine) repeat forever
and are called Periodic Functions.

The Period goes from one peak to the next (or from any point to the next matching point):

The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.

The Phase Shift is how far the function is shifted horizontally from the usual position.

The Vertical Shift is how far the function is shifted vertically from the usual position.

All Together Now!

We can have all of them in one equation:

y = A sin(B(x + C)) + D

• amplitude is A
• period is 2π/B
• phase shift is C (positive is to the left)
• vertical shift is D

And here is how it looks on a graph:

Note that we are using radians here, not degrees, and there are 2π radians in a full rotation.

Example: sin(x)

This is the basic unchanged sine formula. A = 1, B = 1, C = 0 and D = 0

So amplitude is 1, period is 2π, there is no phase shift or vertical shift:

Example: 2 sin(4(x − 0.5)) + 3

• amplitude A = 2
• period 2π/B = 2π/4 = π/2
• phase shift = −0.5 (or 0.5 to the right)
• vertical shift D = 3

In words:

• the 2 tells us it will be 2 times taller than usual, so Amplitude = 2
• the usual period is 2π, but in our case that is 'sped up' (made shorter) by the 4 in 4x, so Period = π/2
• and the −0.5 means it will be shifted to the right by 0.5
• lastly the +3 tells us the center line is y = +3, so Vertical Shift = 3

Instead of x we can have t (for time) or maybe other variables:

Example: 3 sin(100t + 1)

First we need brackets around the (t+1), so we can start by dividing the 1 by 100:

3 sin(100t + 1) = 3 sin(100(t + 0.01))

Now we can see:

• amplitude is A = 3
• period is 2π/100 = 0.02 π
• phase shift is C =0.01 (to the left)
• vertical shift is D = 0

And we get:

Frequency

Frequency is how often something happens per unit of time (per '1').

Example: Here the sine function repeats 4 times between 0 and 1:

So the Frequency is 4

And the Period is 14

In fact the Period and Frequency are related:

Frequency = 1Period

Period = 1Frequency

Example from before: 3 sin(100(t + 0.01))

The period is 0.02π

So the Frequency is 10.02π = 50π

Some more examples:

When frequency is per second it is called 'Hertz'.
