How start quickly with GnuPG ?

Hi,

I would like to use Gnupg to encrypt, sign... documents.

I've downloaded the Manual, it's quite extensive. So the learning curve is proportional :)

I've tried the GPA GUI, but with it, it seem impossible to generate an ECC key..

So what would be your recommendation to be able to generate ECC keys, be able to encrypt, sign etc.. with or without GUI.

Thanks.
