Function Keys
Keys labelled from F1 to F12 are function keys. These are sets of keys on a computer keyboard that perform specific
functions within software applications and the operating system. Their functions differ from program to program. For
example: F1key in most programs is to get help on that program.
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 allow 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 to the start of a document. The End key moves the cursor to the end of a line of text or
to 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 BACKSPACEkey 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 most Windows-compatible keyboards.
