How does one make clickable links to execute MATLAB commands from Simulink?

When I annotate the following line in Simulink

<a href="matlab:1+1">add</a>

I get it in text form. It doesnt even get converted into a link let alone run the Matlab command.

How does one make clickable links in Simulink? I have seen them in almost all of the Simulink examples.

I searched a lot. Where is the documentation for this? It is really frustrating.

this string works in MATLAB Command Window. Copy and past the above string in MATLAB and hit return. You will see an error message but the hyper link of "add" will be there. Click it and you get "2" as the answer.

Run 'sl_subsys_semantics' in Command window to open the example model. Any block can be double clicked to open another model. Right click any block, select "properties..." then "Callbacks" tab, then select the "OpenFcn" and you will see a command. It could be a Simulink model name, or a MATLAB script. This is one of the ways to run a MATLAB Command in Simulink by clicking.
