Alternatively referred to as Control I and C-i, Ctrl+I is a shortcut key most often used to italicize and un-italicize text.


On Apple computers, the shortcut for italic may be the Command key+I keys.

How to use the Ctrl+I shortcut key

To use the keyboard shortcut Ctrl+I, press and hold either Ctrl key on the keyboard and while continuing to hold, press the "I" key with the same hand or the other hand.

With this keyboard shortcut, if no text is highlighted and the program you're using uses this key to italicize text, pressing the shortcut key turns on and off the italic feature. If text is highlighted, the highlighted text will become italic or un-italic, if already italicized.


On Apple computer keyboards, the Ctrl key is labeled as "control."

Ctrl+I in an Internet browser

In the Edge, Firefox, IE, and some other Internet browsers, pressing Ctrl+I opens the bookmarks or favorites sidebar.

Ctrl+I in Excel and other spreadsheet programs

In Microsoft Excel and most other spreadsheet programs, pressing Ctrl+I when one or more cells is highlighted will italicize or un-italicize the selected cells. If editing the contents of a cell with no selected text, Ctrl+I turns on and off italic for all contents of the cell.


You can also use the Ctrl+3 shortcut to italicize text in Excel.

Ctrl+I in Microsoft PowerPoint

Pressing Ctrl+I in Microsoft PowerPoint does one of the following functions, depending on your current view.

  1. In the Normal view, italicize highlighted text.
  2. In the Slide Show view, change the normal cursor to the highlighter tool. Click and hold the mouse button to use the highlighter on the screen.

Ctrl+I in Word and other word processors

In Microsoft Word and other word processor programs, highlighting text and pressing Ctrl+I makes the text italic. If the text is already italic, highlighting the italicized text and pressing Ctrl+I un-italicizes the text.
