Isn't the solution that of giving up the idea of "matching $"? The  
main use I
see of the double-clicking device is when there is an error in the  
Latex code,
so that even the less ambitious idea of finding the "following $"  
would be
useful.

More suggestions for the preview window:
1) a key command for "go to page" --- there is already a "go to line"
     command in the text windows, and the same widget could be used,
     so that it could be easily implemented. (This has been mentioned  
before)
2) control +  and control - for changing the magnification. This is
     a standard shortcut in Adobe reader and in Photoshop.
     Is anybody attached to the "rotate clockwise" or
     "rotate anticlockwise" shortcuts? (or even using them?)
3) shortcuts for "next-page" and "previous page". At present left- 
right arrows
     work, but only when the focus is on the window pane, and not on  
one of the
     text fields in the toolbar. If the shortcuts in (1) or (2) were  
implemented
     one could avoid moving the focus point to the text fields, and  
(3) would be
     less urgent.
4) the third text field on the toolbar should not be there, as it is not
     editable. (Just an aesthetic remark.)

Thanks,
