SelectTextAreaText - Cursor on the left Side?

Hi there!
I have a problem with the SelectTextAreatText command.
If i use it, the cursor position will be on the right Selectionside but i want it on the left.
How can i realize it?

Here is some Code:

SuperStrict
Framework BRL.Win32MaxGUI
Import BRL.EventQueue
Import BRL.StandardIO

Local window:TGadget = CreateWindow("Window",320,320,480,480)
Local text:TGadget = CreateTextArea(0,0,window.clientwidth(),window.clientheight(),window)

text.setlayout 1,1,1,1
ActivateGadget text
SetTextAreaText text,"   Line 1~n   Line2~n   Line3"
SetGadgetFilter text,FilterKey,text

Repeat
   WaitEvent()
Until EventID()=EVENT_WINDOWCLOSE

Function FilterKey:Int(event:TEvent,context:Object)
   Local this:TGadget
   Local id:Int,key:Int,mods:Int
   id=event.id
   key=event.data
   mods=event.mods
   this=TGadget(context)
   If id=EVENT_KEYDOWN
      If key=KEY_HOME
         Local cursorpos:Int = TextAreaCursor(this)
         Local pos:Int = TextAreaChar(this,TextAreaLine(this,cursorpos))
         Local line:String = TextAreaText(this,TextAreaLine(this,cursorpos),1,TEXTAREA_LINES)
		 Local sellen:Int = TextAreaSelLen(this)
         For Local i:Int=0 Until line.length
            If Not IsSpace(line[i])
			   i:+pos
               If i<>cursorpos
                  If mods=1
					 SelectTextAreaText this,i,0
                     SelectTextAreaText this,i,cursorpos-i+sellen
                  ElseIf mods=0
                     SelectTextAreaText this,i,0,TEXTAREA_CHARS
                  Else
                     Return 1
                  EndIf
               Else
                  If mods=1
					 SelectTextAreaText this,pos,0
                     SelectTextAreaText this,pos,cursorpos-pos+sellen
                  ElseIf mods=0
                     SelectTextAreaText this,pos,0,TEXTAREA_CHARS
                  Else
                     Return 1
                  EndIf
               EndIf
               Exit
            EndIf
         Next
         Return 0
      EndIf
   EndIf
   Return 1
EndFunction

Function IsSpace:Byte(char:Byte)
   Return char<=32 And char<>"~n"[0]
EndFunction

Navigate with the cursor is like hell if its on the right selectionside (after you use SHIFT+HOME) while pressing UP and DOWN.

Hope for help.
