# Shared Features: Predefined Function Keys

Vehicle Spy comes with keyboard function keys F1 - F5 predefined with useful features as shown in Table 1. The remaining keys F6 - F12 can be assigned to Vehicle Spy features like [Widgets](/vspy-3-documentation/shared-features-in-vehicle-spy/shared-features-widgets.md), Transmit Messages, [Diagnostic Jobs](/vspy-3-documentation/vehicle-spy-main-menus/main-menu-spy-networks/diagnostics/diagnostics-setup.md), and [Function Blocks](/vspy-3-documentation/vehicle-spy-main-menus/main-menu-scripting-and-automation/function-blocks/function-blocks-types/function-blocks-hotkeys.md) using their own hotkey pulldown lists.
