Thread of questions

[Stomach Pulser]

I will use this thread to ask questions about how different pieces of code work. No need in making new topics each time. First off:

I am adding a chat box where users input text instead of bltign it to the screen. It works successfully, but i can't make any sense of this code:

Code:

frmMirage.txtInputChat.Text = MyText
    If Len(MyText) > 4 Then
    frmMirage.txtInputChat.SelStart = Len(frmMirage.txtInputChat.Text) + 1
End If

I am trying to figure out how it works and what everything in it means. Any tips?
