Please add r1 Page Down and End to numpad kit to support 1800 layouts.

You'll need to add those keys (to the numpad kit) if you want to support 1800/CP/96-key boards.
I also recommend adding a 1u
= key to the numpad kit, on R4 (R1 in standard numbering). This is a becoming a regular thing in EPBT sets, which is a good thing because it completes that 1800 support and also works well for Mac layouts.
