CDDWinLeft, CDDWinTop, CDDWinWidth, CDDWinHeight

CDDWinLeft = nnnn, CDDWinTop = nnnn, CDDWinWidth = nnnn, CDDWinHeight = 
nnnn:  These values set the position and size of the popup window used by 
extended directory searches, in characters, including the border.  The 
defaults are 3, 3, 72, and 16, respectively (i.e., a window beginning in 
column 3, row 3, 72 columns wide and 16 rows high).  The position is 
relative to the top left corner of the screen.  The width and height 
values include the space required for the window border. 

The window cannot be smaller than than 10 columns wide by 5 rows high 
(including the border).  The values you enter will be adjusted if 
necessary to keep a minimum-size window visible on the screen. 

The window is normally displayed with a shadow, but if you specify a 
window starting at column 0 and extending to the right margin, the shadow 
is eliminated; this may be useful to prevent speech software from reading 
text in the shadow area while viewing the window.
