How to Turn Off Function Key in AutoCAD?

Step-by-Step Guide to Disable the Function Key in AutoCAD

To effectively manage function keys in AutoCAD, it’s crucial to know how to disable the Function (Fn) key. This allows users to access the standard function key actions without interference from alternative commands assigned to those keys. Below is a detailed guide to turning off the Fn key on your device.

Accessing System Configuration

1. Power On Your Computer
   Ensure that your computer is turned on and fully operational before proceeding to the next steps.

2. Enter BIOS Setup
   Restart your computer and press the designated key (often F10, Esc, or Del depending on the manufacturer) during the boot process to access the BIOS setup menu.

3. Navigate to System Configuration
   Within the BIOS menu, use the right arrow key to highlight the “System Configuration” section.

Modifying Action Keys Mode

1. Locate Action Keys Mode
   Once in the System Configuration menu, press the down arrow key to find the “Action Keys Mode” option.

2. Change Settings
   Select the Action Keys Mode option and press “Enter.” Change the setting from “Enabled” to “Disabled.” This adjustment will ensure that the function keys operate as standard keys without needing to hold down the Fn key.

Setting Function Keys in AutoCAD

For users aiming to use standard function keys within AutoCAD, follow these instructions:

1. Open Control Panel
   Navigate to your computer’s Control Panel. You may search for it directly if you are using Windows.

2. Select Bootcamp (If Applicable)
   If you are on a Mac running Bootcamp, choose the option labeled “Bootcamp.”

3. Access Keyboard Settings
   Click on the “Keyboard” tab. You should find an option called “Use all F1, F2, etc. keys as standard function keys.”

4. Activate Standard Function Key Mode
   Enable the checkbox next to this option to allow direct use of the function keys in AutoCAD without pressing the Fn key.

Understanding Function Keys in AutoCAD

The function keys offer various commands that are integral to the AutoCAD environment. Here are some common functions:

• F8 Key: This key activates the ORTHO mode, which restricts cursor movement to horizontal and vertical lines. This is particularly useful for drawing straight lines at 90-degree angles.

• F12 Key: This key activates the Dynamic Input feature, simplifying input for coordinates and measurements during drafting.

Customizing Function Keys in AutoCAD

To tailor the functionality of your function keys further:

1. Open Shortcut Keys Dialog
   In AutoCAD, navigate to the Command User Interface (CUI) by typing CUI in the command line and pressing Enter.

2. Select Keyboard Shortcuts
   In the CUI dialog, expand the “Keyboard Shortcuts” section.

3. Choose Key Assignment
   Click on “Shortcut Keys” in the left pane. Here you can adjust or assign new commands to your preferred function keys.

4. Assign a New Command
   Select the desired function key, such as F4, and associate it with a command of your choice by modifying its properties.
