Hov to change tab?

[felldin]

I'm trying to do an installation script. During the installation a window appear. In this window I would like to "click" another tab than the current so that I can change the settings under that tab. The question is just how I change tab? I just cant find the function.

If it is a custom control that looks like a standard tab... creativity should ensue.

For example:

Send("^{TAB}")

for this eventuality.
