Which of the following shortcut keys insert a hyperlink in M.S Office?

In Microsoft Word, each common formatting or editing command is bound to a fixed Ctrl + letter combination, and the same combination performs the same action wherever it is used in the document.

The command that inserts a hyperlink — linking selected text or an object to a web address, file, or a location inside the document — is bound to Ctrl + K, and this particular shortcut is consistent across Word, Excel, and PowerPoint.

In MS Word, comparing all four shortcuts by what each one actually does:

• Ctrl + K opens the Insert Hyperlink dialog box (same in Word, Excel, and PowerPoint).

• Ctrl + M applies the Increase Indent command, moving the selected paragraph one tab stop away from the left margin.

• Ctrl + J applies Justify alignment, spacing the paragraph so both its left and right edges line up with the margins.

• Ctrl + D opens the Font dialog box for character formatting such as style, size, and effects.

Only Ctrl + K performs the hyperlink-insertion action asked about in the question, so Ctrl + K is the shortcut that inserts a hyperlink in M.S Office.
