The Shift key on the iPad’s onscreen keyboard has a short arrow pointing up on the key cap: By default, the keyboard letters will actually switch between lowercase and uppercase when the Shift key is pressed. There is an option in Settings Gener. see Keyboard Menu/App Key Mac doesn't have Menu key. If you use a Windows keyboard on a Mac, the Menu key does Ctrl+p. see Mac Keyboard Tools Main Return/Enter Key Apple keyboard (A1242), year 2009. Note the return/enter key, with dual labels. see Apple Keyboards ⌨ image source On PC keyboard, the main enter key is labeled “Enter. Choose File Load Existing Keyboard. Select the keyboard you want to see. Find the country or region name in the keyboard list that's followed by '(Apple)'. Follow the instructions provided with the app. You can print images of the keyboard, including what keys look like when holding modifiers like Shift, Option, or Fn.
In computing, a modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed together. By themselves, modifier keys usually do nothing; that is, pressing any of the ⇧ Shift, Alt, or Ctrl keys alone does not (generally) trigger any action from the computer.
For example, in most keyboard layouts the Shift key combination ⇧ Shift+A will produce a capital letter 'A' instead of the default lower-case letter 'a' (unless in Caps lock or Shift lock mode). A combination of Alt+F4 in Microsoft Windows will close the active window; in this instance, Alt is the modifier key. In contrast, pressing just ⇧ Shift or Alt will probably do nothing unless assigned a specific function in a particular program (for example, activating input aids or the toolbar of the active window in Windows).
User interface expert Jef Raskin coined the term 'quasimode' to describe the state a computer enters into when a modifier key is pressed.

Modifier keys on typewriters[edit]
- ⇧ Shift
Modifier keys on personal computers[edit]
The most common are:
- ⇧ Shift
- Ctrl (Control)
- Alt (Alternate) – also labelled ⌥ Option on Apple Macintosh keyboards
- AltGr (Alternate Graphic)
- ◆ – Meta key, found on MIT, Symbolics, and Sun Microsystems keyboards
- ⊞ Win (Windows logo) – found on Windows keyboards
- ⌘ Command – Command key, found on Apple Macintosh keyboards. On older keyboards marked with the Apple logo.
- Fn (Function) – present on small-layout keyboard, usually on notebooks.
The (Sun) Meta key, Windows key, (Apple) Cmd key, and the analogous 'Amiga key'(A) on Amiga computers, are usually handled equivalently. Under the GNU/Linux operating system, the desktop environment KDE calls this key Meta, while GNOME calls this key, neutrally, Super. (This is a bit confusing, since the original space-cadet keyboard and the X Window System recognize a 'Meta' modifier distinct from 'Super'.)
The Sinclair ZX Spectrum has a Symbol Shift key in addition to Caps Shift. This was used to access additional punctuation and keywords.
The MSX computer keyboard, besides Shift and Control, also included two special modifier keys, Code and Graph. In some models, as in the Brazilian Gradiente Expert, the Code and Graph keys are labelled 'L Gra' and 'R Gra' (Left and Right Graphics). They are used to select special graphic symbols and extended characters.
Shift Key Definition
Likewise, the Commodore 64 and other Commodore computers had the Commodore key at the bottom left of the keyboard.
Compact keyboards, such as those used in laptops, often have a Fn key to save space by combining two functions that are normally on separate keys. On laptops, pressing Fn plus one of the function keys, e.g., F2, often control hardware functions. Keyboards that lack a dedicated numeric keypad may mimic its functionality by combining the Fn key with other keys.
The MITspace-cadet keyboard had additional Top, Front, Super and Hyper modifier keys. Combined with standard modifiers, it could enter as many as 8,000 different characters.
Accented characters[edit]
Some non-English language keyboards have special keys to produce accented modifications of the standard Latin-letter keys. In fact, the standard British keyboard layout includes an accent key on the top-left corner to produce àèìòù, although this is a two step procedure, press the accent key and release, then the letter key. These kinds of keys are called dead keys. The AltGr modifier produces the áéíóú sequence, or in conjunction with the Shift key, ÁÉÍÓÚ. Keyboards of some languages simply include the accented characters on their own keys. Some keyboards also have a Compose key for typing accented and other special characters. By pressing Compose, and then two other keys, something similar to a combination of the glyphs of the two previous keys will appear on the screen.
Dual-role keys[edit]
It is possible to use (with some utility software) one same key both as a normal key and as a modifier.
For example, you can use the space bar both as a normal Space bar and as a Shift. Intuitively, it'll be a Space when you want a whitespace, and a Shift when you want it to act as a shift. I.e. when you simply press and release it, it is the usual space, but when you press other keys, say X, Y and Z, while holding down the space, then they will be treated as ⇧ Shift plus X, Y and Z.
The above example is known as 'SandS', standing for 'Space and Shift' in Japan.[1] But any number of any combinations are possible.[2]
To press shift+space in the previous example, you need in addition to a space/shift dual role key, one of (a) another space/shift key, (b) a usual shift, or (c) a usual space key.

This page discuss differences between Apple Keyboard and Windows keyboard.
On the PC keyboard, you have the Ctrl (Control key), ❖Window (Windows logo key), Alt (alternate key).
On Apple keyboard, you have Ctrl, ⌥option (alt/option), ⌘command (command) keys.
Control Key
Control Key in Microsoft Windows
The Control Key in Windows is used for keyboard shortcuts. For example, Copy is Ctrl+c, Paste is Ctrl+v.
On the Mac, Command key is used for keyboard shortcuts. Copy is ⌘command+c, Paste is ⌘command+v.
Control Key in Mac OS X
The Control key under Mac is rarely used.When used, it is as a modifier in combination with other modifier keys. For example,in Safari (as of 2018-05-01)Ctrl+⌘command+1 show bookmarks sidebar.
Mac OS X by default supports emacs basic cursor movement keybindings.You can try it in TextEdit.They are:
Names Of Keys On Keyboard
Mac OS X's default emacs keybindings:
- Ctrl+f → move forward
- Ctrl+b → move backward
- Ctrl+n → move down a line
- Ctrl+p → move up a line
- Ctrl+a → beginning of line
- Ctrl+e → end of line
- Ctrl+k → delete current position to end of line
- Ctrl+y → paste
Alt/Option Key
⌥option on Apple keyboard and Alt on PC keyboards both send the same USB scancode.
Alt Key Use in Microsoft Windows
The Alt key in MS Windows has several different uses:
- It is used to invoke graphical menus. For example, pressing (and releasing) Alt by itself will activate the graphical menu, then the user can press a alphabetic key to invoke a menu command or use arrow keys to navigate the menu.For example,Altec invokes the copy command in edit menu, in Notepad and most other Microsoft Windows apps.
- When pressed simultaneously with a key, it invoke a command directly. For example, Alt+F4 closes the current window.
- When held down then type a number on the numeric keypad, it enters a special character. For example, hold Alt then type 0225 on numeric keypad will insert “á”.[see How to Input Unicode]
- If your Windows's keyboard layout is set to a European language, then right Alt plus a letter key inserts special characters.[see International Keyboard Layouts][see Alt Graph Key, Compose Key, Dead Key]
Option Key Use in macOS
The ⌥option key is used for:
- Cursor control, with arrow keys. For example, ⌥option+→ moves cursor by word.
- Option key is used to insert special characters, such as “• ™ ©”. For example, ⌥+8 will insert the bullet character “•”. [see Mac Keyboard Viewer]
- Option key is used as a modifier key together with the ⌘command key. For example, in ⌘command+⌥option+h invokes the command 〖Hide Others〗 in all Apple applications.
Windows Logo Key and Apple Command Key
All Keys On A Keyboard
❖Window and ⌘command both send the same USB scancode.
Their behaviors are different in Mac and Windows.
In Windows:
- Microsoft logo key invokes the Start menu.
- When pressed with letter key, it invokes a command that's meaningful system-wide. For example, ❖Window+d gets you the desktop.
[see Windows Keyboard Shortcuts]
Under Mac, the Command key is used as a modifier key to invoke shortcuts. For example, ⌘command+c is Copy. It is similar to MS Window's use of the Ctrl key.
Menu/App Key
[see Microsoft Keyboards Gallery]
The ▤Menu key, also called Application key, is invented by Microsoft. Typically only on the right side. It is used for Context Menu. The key's function is similar to the mouse's right button, or pressing Shift+F10 in most applications.
[see Keyboard Menu/App Key]
Mac doesn't have ▤Menu key. If you use a Windows keyboard on a Mac, the ▤Menu key does Ctrl+p.
[see Mac Keyboard Tools]
Main Return/Enter Key
On PC keyboard, the main enter key is labeled “Enter ↵”.
On Apple's keyboards, the main enter key is usually labeled “return” or just by a symbol “↩”.
Note: the main enter/return key is different from the Enter on number keypad. (it sends a different key signal.)
Enter/Return Key Conventions
In Microsoft Windows desktop (Explorer), when a file is selected, Enter will open the file.(To rename the file, press F2.)
In Mac desktop (Finder), when a file is selected, Enter will activate file rename.(⌘command+o to open the file.)
Backspace Key
On PC keyboards, there is a Backspace key on the main section.
On Apple keyboards, this key is labeled “delete”.
Backspace Key Conventions
When in text editing, the Backspace is used the same way in both OS X and Windows. It delete texts to the left of the cursor.
In browser, Windows useBackspace key to “go back” to a previous visited page.For some time around 2005 to 2013, Mac OS X's Safari browser also started to do the same, but removed this shortcut again when gesture with touchpad becomes popular. Use 2-finger swipe to the left to go back.
Delete/Del Key
The Delete ⌦ key is located in the Home/End key cluster. This key sometimes labeled “Del”.
On Mac, this key is labeled “delete” or ⌦.
On Windows, Delete ⌦ is often used to delete things. For example, on desktop, select a file, pressing Delete ⌦ will put the file to the “Recycle Bin”. In a text editor, the key will delete to the right of the cursor.
On the Mac, from early 1990s to 2006, the Delete ⌦ key is almost never used, even in text editors. When there is a function assigned to it, it is used to delete to the right of the cursor. Apple keyboard keycaps.
Insert Key
On PC keyboards, there is the Insert key (sometimes labeled Ins). Apple keyboards doesn't have this key.
PrtScn ScrLk Break vs F13 F14 F15
The PC has these keys:PrintScreen/SysRq,ScrollLock,Pause/Pause.
These keys have old history back to the 1980's (or earlier) and in generalare not used since 1990, except on Windows the PrtScn key is for screenshot.
[see Print Screen, SysRq, ScrLk, Pause, Break Keys]
Which Is The Shift Key On Apple Keyboard Keys
Apple's keyboards do not have these keys. On some Apple keyboards, they have F13, F14, F15 instead. “Apple Keyboard with Numeric Keypad” of 2009, has F16 to F19.
The {PrintScreenScrollLockBreak} are different keys than {F13F14F15}. They do not send the same signals. In any case, when either PC keyboard or Apple keyboard is plugged in on a Mac running Mac OS X 10.4, these keys have the same behavior (could be due to operating system).
Numeric Keypad Keys
Which Is The Shift Key On Apple Keyboard Shortcuts
The numerical keypad keys send different USB scancode than the samekeys at top row of the main key section.
However, on macOS, the number pad keys are remapped to be the same as the number keys on the main section of keyboard.
The difference between PC and Mac keyboard's number pad are:
- The arrangement of plus minus multiply divide keys are different.
- PC keyboard has NumLock key. Apple keyboard does not have Number Lock toggle.
- Apple keyboard has clear.
- Apple's Numeric keypad has a equal = key.
