How can I select multiple vertices and create faces with a single command If I am not wrong once I saw a tutorial, in which something similar was done, but I do not remember, as it was, nor, the tutorial that was, I leave some captures to better understand what I want to do. 

I hope you can to understand me and I'm sorry for my bad english.



I know I can do this by selecting the vertices and pressing the f



But how can I do it by selecting multiple verties and doing them all at once, with a single command.
There is a command called Grid Fill which sort of does this, might be what you are looking for.

There is also an add-on included with Blender called F2 which (amoung other things) makes filling rows of faces easier. Have a look for some demos of how to use this on Youtube, it is a big time saver.
