And for the people who rather like to use shortcuts and have Poser 7 or later:

You can assign a keyboard shortcut to a script in the scripts menu. You just need to change the filename like in the following examle:

From "myscript.py" to "myscript ###Shift+Alt+Ctrl+p.py" and voilà (that means after restarting Poser...) you can run the script by pressing the Alt, Ctrl, Shift and p keys at the same time.
