A keyboard layout that you are familiar with that has a numeric keypad... I like my IBM KU-0225... it looks like this: https://i5.walmartimages.com/asr/3038865f-6e35-4e01-9dd7-392... .... it has almost the same layout as IBM model M but with Windows keys and context menu key (I strictly use Linux and I use the Windows keys a lot)
