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.)

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.)

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 use Backspace 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.

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 general are not used since 1990, except on Windows the PrtScn key is for screenshot.

[see Print Screen, SysRq, ScrLk, Pause, Break 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 {PrintScreen ScrollLock Break} are different keys than {F13 F14 F15}. 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).
