ActivateWin gives to Shell some Intuition's handling on windows and screens. 

        TITLE           Title(s) of the window(s)/screen(s) on which to operate
                        (activate window is the default). Wildcards allowed
        LIST            List screens and windows titles while scanning
        QUIET           Don't complain when (TITLE) is not found, and don't
                        output window/screen's title when it's found
        CURRENT         Act on currently active window/screen
        DONOTBUT        Do not activate found window/screen but do other things
        HIDE            Make found window(s) invisible (no other operation will 
                        be done on them!)
                        When omitted, invisible window(s) is(are) made visible
        MX  = MOVEX     Move found window(s)/screen(s) horizontally (pixels)
        MY  = MOVEY     Move found window(s)/screen(s) vertically (pixels)
        SX  = SIZEWINX  Resize found window(s) horizontally (add/sub pixels)
        SY  = SIZEWINY  Resize found window(s) vertically (add/sub pixels)
        ALT = ALTCOORDS Let MX and MY mean coordinates relative to origin,
                        and SX and SY mean real size of window (TITLE)
        TOFRONT         Bring found window(s)/screen(s) to front
        TOBACK          Bring found window(s)/screen(s) to back
        CLOSE           Try to close found window(s)
        SCREEN          Act on screen (TITLE): CURRENT, MX, MY, TOFRONT and
                        TOBACK arguments are recognized when using this switch

Those arguments are shown from the Shell by typing:
"ActivateWin ?"
followed by a new "?".


EXAMPLES

    ActivateWin HIDE #?Shell
        will hide all the Shell windows currently opened (just open a new Shell
and type: "ActivateWin #?" to bring them back visible).

    ActivateWin CLOSE CURRENT
        will try to close the currently active window, ie probably the Shell
window in which you type the command ;-)

    ActivateWin "AROS-Shell" MX=-15 ALT
        will activate and put the front-most Shell window 15 pixels at the left
of the left-side of the screen

    ActivateWin SCREEN DOPUS#? MY=150
        will drag down 150 pixels of their current position all screens of all
instances of Directory Opus. The currently active window won't be changed.
