One hit kill command?

What command do i enter to use the one hit kill?

i copied these in (from someone who suggested them):
Bind "DEL" "cc_send_start_game_message;cc_change_start_ga me_m essage"
bind f1 "ohk;godmode;cc_set_sub_weapon javelin_lvl2 999"
bind f2 "host_timescale 3"
bind f3 "changelevel 2"
bind f4 ";godmode;cc_set_sub_weapon javelin_lvl2 999"
bind f5 ";godmode;cc_set_sub_weapon mining_bomb 999"
bind f6 "cc_change_figure_height 1000"
bind f7 "cc_change_figure_height 0.1"
bind f8 "godmode;cc_set_sub_weapon sticky_bomb 999"

and none of them have one hit kills. (and whats the height do??)

ohk is one hit kill just press f1 and you're good to go. The height is pretty much self explanatory, also make sure to use the hacks alone because it won't work if you are in a party. happy hacking
