AutoHotkey to remap a laptop numpad to the keys you'd find in the navigation cluster

#persistent
#SingleInstance Force

; The idea here is to remap the entire numpad (with Numlock off)
; to a scroll lock area with:
;       Ins   Home  PgUp
;       Del   End   PgDn
;       Up    Up
; Left  [  Down  ]  Right
;
; where we unfortunately borrow the Right arrow key left of the numpad,
; to be the Left arrow key instead.

NumpadRight::PgDn
NumpadUp::Home
; vk0C = Numpad5 when not in Numlock mode
vk0C::End
NumpadHome::Insert
NumpadLeft::Delete

NumpadDel::Right
Right::Left
; Numpad0/Ins is a double-wide key, unfortunately
NumpadIns::Down
; Two up keys above the down key
NumpadDown::Up
NumpadEnd::Up
; Disable unused keys
NumpadPgDn::return
NumpadEnter::return
NumpadAdd::return
