Shortcut for email to a specific person I am new to Android, and would like to know whether it is possible to add a desktop shortcut so that when I press it, I can send an email to a specific person, and I just need to put the subject and send it.
Not for a specific person -- but still a shortcut, which simply opens the "compose new mail" screen: Compose Mail Shortcut. There's also Send Mail Shortcut which, from the name, sounds to exactly fit your purpose -- but as it helds no description at all, it's hard to tell. Last but not least: Mail Linker even seems to fit right from its description.

Unfortunately, as already mentioned, there's no such thing provided by the Android core system by default.
