Attaching custom escape sequence to kHome key

My idea is to attach an action in vim to kHome key (Home located on numeric keypad) that will not affect ordinary Home key. In terminal I run:

Code:$ cat
# pressed kHome
^[[1~
# pressed Home
^[[1~So, Home and kHome give the same escape sequence. I decided to attach my own escape sequence to kHome.
Code:$ showkey
# pressed kHome
keycode 71 press
keycode 71 release
# pressed Home
keycode 102 press
keycode 102 releaseSo, kHomes code is 71. I created a file ~/funcskeys:
Code:keycode 71 = F13
string F13 = "\033[1;5G"I don't fully understand how custom escape sequences should be constructed, so I created it using an old answer and examples from the Internet. Then I ran as root:

Code:# loadkeys -c ./funcskeysWhen I run cat again I still get the old escase sequence:
Code:$ cat
# pressed kHome
^[[1~What's wrong? Maybe, I need to delete the old escape sequence from the key first?
