Is that a serious question? Search for "Special Characters" in the documentation.

For reference:

.' is the transpose() operator that does NOT do conjugate transpose

{:} is for cell arrays. f(A{:}) is the same as if you had written

f(A{1}, A{2}, A{3}, A{4}, ...., A{end})

In particular, A{:} expands to a sequence of different arguments to whatever it is being called for.
