VIM: how to append yanked text to unnamed register

Question

I know \"Ayy can append current line to register a.

How do I append current line to unnamed register?

Answer 1

You can use this

:let @"=@".getline('.')

to append to the unnamed register. I do not believe there is a keyboard shortcut to do this. (However you could create a mapping if you wanted.)

The reason I say that there is no keyboard shortcut for this is because :h quote_alpha only talks about uppercase letters (for appending). And there is no equivalent statement in :h quote_quote
