The "F" keys, or functions keys, on a Dell Laptop D430 operate default functions that are defined by Windows. However, the keys on the D430 are similar to many laptops in that many of the keys have secondary functions that can be enabled by pressing the "Fn" key along with the "F" key.

    Press F11 to expand the selected window or program to fill the screen.

    Press F12 to open the "Save As..." box in some Windows programs.

    Pres Fn and F8 to allow video to be displayed on a second monitor if it is connected to the laptop via the connector on the back of the D430.

Tips and warnings

  • To ensure that all the secondary functions work, be sure to install any Dell drivers and software included with your D430. The primary functions for the F keys can be superseded by different programs and will not work the same way with every program.
