29 | ;;; The terminal intialization C code file might have initialized |
30 | ;;; function keys F13->F60 from the termcap/terminfo information. On | |
31 | ;;; a PC-style keyboard these keys correspond to | |
32 | ;;; MODIFIER-FUNCTION_KEY, where modifier is S-, C, A-, C-S-. The | |
33 | ;;; code here subsitutes the corresponding defintions in | |
34 | ;;; function-key-map. This substitution is needed because if a key | |
35 | ;;; definition if found in function-key-map, there are no further | |
36 | ;;; lookups in other keymaps. | |
