VADDS and Vetstar utilize ProIV programming, and the ProIV kernel prompt allows navigation directly to specific screens within the program.  Normally this can be initiated by hitting Ctrl + Fn + Break on standard keyboards.  However, some newer model laptops do not have the Pause/Break key.  The following substitutes may be used.

Logitech Keyboards need only Ctrl + Break to work.

For the Dell Laptop Latitude model 5490 use the Ctrl+Fn+B option.
