Hi 
I created this function which works well.

 (defun z/org-sparse-todo ()
    (interactive)
    (org-match-sparse-tree t "+TODO=\"TODO\""))

my question is how can i match on ANY todo state and not just literaly TODO
ie if i have this in my org file 

#+TODO: TODO(t) EXP(e) | SUBMITTED(s) K_TRACK(k) PAUSED(p) DONE(d) 

how can i match it by all the todos like TODO and EXP

Best
