[xcrysden] How to choose special direction with xcryden in WIEN2k

Dear Sir

   I working on a hexagonal system and I hope to plot
the calculated  band structure in  the following
special directions (Using Wien2k) 
   
  1-A(001)          2-Delta(0 0 1/2)   3-GAMMA (0 0 0)
  4-Sigma(1/3 0 0)  5-Sigma(2/3 0 0)   6-M(100)
  7-U(1 0 1/2)      8-L( 1 0 1)

  I tried the following too 2 steps (A&B) at the
interface of wien2k

 A- Generate k-mesh using your wonderful program
XCrysden then  save case.klist as xcrysden.klist
 B- append tempelate to case.in1 from xcrysden

   My problem with that is after step A the Brillouin
zone (Hexagonal) appear with your program but I could
not figure how to put the above special
directions(1-8) I pointed my mouse on the plotted
Brillouin zone
points but It never wrote one of the above directions 
(May be my understanding of choosing those points is
very limited)
   I hope you can direct me and tell what I am doing
wrong to solve  this problem if it is possible with 
xcrysden

  With my best regard 
   I am hoping to  hear all your kindly advice and
comments
