Keyboard shortcut

Hello, I would like to know if there is any keyboard command which goes from a field on left side of my Navision (Hystory) to the field just below. For Example in my Navision I see ITEMS and below there is PRODUCTION BOM…I want to know if there is any Keyboard shortcut to go from one to the other because I’m using a VBA code that send some command to Navision to handle some repetitive operations. Thanks a lot!!
