C-i seems to be triggering harpoon can't find the keymap

[kanishkaverma]

Hey, I often use C-i and C-o to navigate between the jumplist. however, it seems that C-i is triggering harpoon and when i try to find the keymap using fk i am not able to find that one for harpoon. Can you please tell me where i can find this or what's setting that map? when i try to look for the map in nmap. i am not able to find it either. Thank you so much for your time.
