I was wondering, is there a way to speed up the game for a short amount of time to be able to skip certain parts of games where you can do nothing but wait?

That is, intros, slow animations, even opponent's turns in turn based games.

For instance, in snes9x, you can hold tab key, and the game would start running super fast, allowing you to skip these wait sequences.

But in dosbox, I haven't found any such feature. You may increase frame skip, but the game only becomes choppy that way.
