This worked in the few tests I did:

(texmacs-modes
(in-inline% (inside? 'math)))

(texmacs-modes
(in-display% (or (inside? 'equation*) (inside? 'equation))))

(kbd-map
(:mode in-inline?)
("d d" (variant-equation (focus-tree))))

(kbd-map
(:mode in-display?)
("d d" (variant-formula (focus-tree))))


First I define two new modes (in-inline and in-display, where for the 
latter one can be inside either a numbered or an unnumbered equation); 
after which I define the keyboard shortcut d d (press twice the D key) 
to have a different effect whether one is in an inline or a displayed 
formula. For the code, I assumed that the code that gets executed when 
one presses the menu button that appears when one is in an equation 
would work here, using the substitution t -> (focus-tree) (assuming that 
the t of the button is the focus tree!). I did not check what the 
variant-formula and variant-equation functions do---I understand faintly 
what the code does, so that it might even be wrong; that means use it at 
your own risk ;-)

By the way I think I have to define the modes because I understood that 
kbd-map is conditional on modes only, but I may be wrong there too.
