MATLAB: ‘Pop-up’ text box – SIMULINK

popupsimulinktext;

Hi,
I would like to implement something in a Simulink Model, what I can click on and which then shows me some text. What I am thinking of is a button, which I can click on and a 'pop-up' appears with the text.
I would like to use it as a 'help' window, where I explain, how I implemented the model.
What I found out so far is that I could use an Annotation with a ClickFcn, looks good, but what would be a MATLAB command which gives me a text 'pop-up'? Or are the totally different solutions?
Thank you!

How about:
helpdlg(sprintf('Some text.\nMore text.'))
