Method of pasting "smoothly-typed" text for demo videos? I often see in demo videos, whenever text is required to be filled in (such as when filling out forms), that the text is entered smoothly, not actually typed by the person shooting the video.

Wondering if anyone knows of a good method(s) of achieving said effect, as it looks much more professional than manually typing text while recording. I'm assuming there is an app(s) that allows someone to paste in text so that it is entered like this, but I can't find anything online so far.
Allmost any video editing software has a "typewriter"-effect or similar called. This one should do exactly what you want and you have the control of several parameters as smoothiness and speed.
