Hiding Commanders that are doing research

[jscott]

I know there is a command to hide commanders who are doing research, but I can't find it in the manual or the pdf of the hotkeys.

What is the command to not show commanders just engaged in research?

Thanks.

Tab. Now if only there was a command to hide scouts/spies on hide. =(

Clarification: the tab key hides researching commanders when you are looking at the army setup screen ('t' or 'y'), not the overland map view.
