Scripts for Vertical Justfication TextFrame

Hi!!

I need your help with this:

Selecting the TextFrame by SELECTION TOOL, I will apply one of these scripts:

1 for vertical justification Top (I will apply the shortcut Alt+T)

2 for vertical justification Bottom (I will apply the shortcut Alt+B)

3 for vertical justification Centre (I will apply the shortcut Alt+C)

4 for vertical justification Justify (I will apply the shortcut Alt+J)

So I have to create 4 sample scripts

The problem, if I create paragraph styles, I can´t apply shortcut Alt+...

Thanks!!!!
