Dell laptops feature a row of hot keys, which are configured to quick-launch an Internet browser, frequently used programs or control speaker from the press of a button. While these hot keys are convenient, many Dell owners find them annoying; the slightest bump to a hot key can accidentally launch a program at the wrong time. If you rarely use hot keys or you find them troublesome, you can turn them off. Disabling Dell hot keys is not permanent; if you want to use hot keys in the future, you can reconfigure your computer to restore the feature.
