A powerful feature for more advanced users (or for SLPs). When you hit Side Talk you are brought to an "entirely new" Talk Suite message window. Whatever you create there will be saved there, while the work you were doing on the original window stays there. Do whatever writing or speaking you want, and when you hit Side Talk a second time, you are brought back to the original screen - and everything in the message window on either "side" of the app will be saved.
