    There are no streams in the traditional sense.  The cmd line output gets sent to
    the cursor location of a document being edited and by using cursor keys, text
    can be injected all over the document.  Sprites can be injected and are not
    serialized!  Furthermore, the input can come from triggering macro widgets.  See
    Doc Overview and Doc Routines.

    If you had a remote term and sent key Scan Codes, the user would press <CTRL-m>
    to access his Personal Menu to trigger his macros.  However, the local
    ~/PersonalMenu.DD might differ from the remote, causing loss of sync between
    local and remote sessions.  Also, the window size of local and remote might
    differ, so word-wrapped text would be different.  Injecting output text with
    different windows sizes would cause remote and local documents to not be in
    sync.

    You can send characters into StdIn.  See In(), XTalk() and InFile.
