Watching sppadde's runs, i've notice their ability to fly through the dialog at insane speeds, but i've yet to be able to find a good way to do this. Dialog in my game seems to be limited to the speed at which it accepts click inputs. Is there a keyboard shortcut or some other trick to help speed the dialog up? Using the GOG build with the default GOG dosbox settings.

Would love to know this.

Oh! Forgot to ever post the solution here. It is simply clicking Left and Right mouse at the same time or rapidly back and forth that speeds things up. I find just pressing them simultaneously works to speed things up quite well.
