Targeting system for a ROM MUD

I had a targeting system on another client that I really liked and I want to duplicate it here since I'm going to be using MUSHClient exclusively now. This is what the output of the MUD looked like:


{T3 AM|714-HP|342-M|330-MV|wilderness|outdoor|(77.22%)}% whe
People near you: 
1: (PK) Graingt A Rubble-Strewn Path in the Mountains 
2: (PK) Jrhurg Upon a Long, Circular Road 
 Eurantic Upon a Long, Circular Road 
3: (PK) Drahka Upon a Long, Circular Road 

{T3 AM|714-HP|342-M|330-MV|wilderness|outdoor|(77.22%)}% s 
The Headwaters of Voralia's Tears 

[Exits: north south] 

{T3 AM|714-HP|342-M|324-MV|wilderness|outdoor|(77.22%)}% t3
------------------------------ 
@TARGET = Drahka 
lt = look | ft = follow | tt = trip | dt = dirt | mt = murder | ht = hit 
hat = hamstring | at = artery | 
F1 = dirt | F2 = trip | F3 = bash | 
F4 = pugil | F5 = leverage | F6 = misdirect | F7 = crescent 
------------------------------

So I could type "where" and see everyone in my PK range. In this example I was 1, Jrhurg was 2, and Drahka was 3. I could type "t3" and Drahka would be set as my target. Then I had aliases set for lt = look target, tt = trip target, so and so forth. If I fought Drahka and killed her I could immediately type "t2" and Jrhurg would be my new target UNLESS I had typed where since the last time and the target numbers had changed. I've just started playing this same MUD again after a 7 year hiatus and I've never used this client before. Can someone walk me through this step-by-step?
