[TxMt] Getting to end of selection in macro

[Dr. Drang]

I am working on an macro in which the selected text will be filtered  
through one command and then all the text after the selection will be  
filtered through another command. After the first command is  
finished, the transformed text is selected, and I need to deselect it  
and put the caret immediately after it. I had thought that hitting  
the right arrow key would do the trick, but found out [that doesn't  
always work][1]. Is there a foolproof way of getting the caret to  
land right after the selection?

And while I'm asking questions, two more:

1. Is there a way for a command to call a macro?

2. Can a macro be made to behave differently depending on whether  
text is selected or not?
