Possible notations for total space of family of types P : A -> U:

  1. \hat P
  2. P\uparrow A, possibly simplified to simply P\uparrow (since A can be read off from the type of P)
  3. no special notation, always write the Sigma-type

(edited to \uparrow for "lying over A")

I vote for Dan's 4. Tot P, with the understanding that one can also use the full Sigma-type whenever useful (this holds for all abbreviations).
