Test case as GardenWorld Admin

• Open Product window

• Click OK to select all products

• The first product is shown: ASSET-Computers, and the focus is on field Search Key

• Navigate with Alt+Right

• Product shown: ASSET-Vehicle, focus still on field Search Key

• Navigate with Alt+Right

• Product shown: Assembly Area, Search Key becomes read-only field, so the focus is lost on the window, focus is put on the browser

• Navigate with Alt+Right -> doesn't work

• Navigate with Alt+Left -> browser message as is interpreted as back in history

A possible solution for this can be to set the focus on the first field available after navigation happens.
When there are no fields available then the focus can be set in the first toolbar button, or some element within the browser

Another strange behavior when navigating: when the record has a detail (for example if the product has a record in Substitute detail tab), then the focus is put on the detail. I think the focus must remain in the master.
