After thinking about it, I think this is what you are trying to do. To quickly switch between Apps press and hold the HOME button on the LCD which will quickly bring up Recent Apps opened. I tried this with a Word Document pulled up in Docs to Go and was quickly able to switch to another App and then I long pressed the HOME button again and I was able to go right back to my Word Document in Docs to Go. The trick is to open up whatever App or Apps you plan on switching between (returning to the Home Screen each time you launch another App) and then finally launch Docs to Go and then press and hold the HOME button to quickly switch between all Apps.
