;; ##### VERY STRIPPED DOWN CONFIG FOR KOMNAD -- Thinkpads (UK ISO) #####

;; US ANSI REPLACEMENT BOARD -- FRU 5N21D68058

;; ISO (UK) board is set to US input so shit is kinda in the usual spot "|\" key (102d) 
;; is mapped to a second left shift. Under US input that key is "<>", but I got that anyway
;; with shifted , and .
