wiki VS nvim-peekup

This is described in :h convert_legacy_function_to_vim9. :h vim9 also recommends https://github.com/lacygoill/wiki/blob/master/vim/vim9.md

As an example, you can cycle between the numbered registers by using a special feature of the dot command which is documented at the help tag "redo-register". I talk a little about it here.

Have a look at the plugin repository, it is a fun way to interact with vim registers, an aspect that is often overlooked by many users.

You could use my plugin (normal mode only) :-)

I understand your concern but ultimately open sourcing projects means exactly that people are free to take them and use/re-write them at will (unless specified otherwise, and even in that case you shouldn't have open sourced it in the first place otherwise). I myself am the author of nvim-peekup and shortly after I published an extremely similar plugin was born (exactly same functionalities, slight minor changes) - I won't cite it because I don't want to spotlight them (but you could find it in any list of nvim plugins nowadays) and because my code being free means people can copy&paste at will.

A plugin that helps with that is nvim-peekup :)

nvim-peekup

someone wrote a sexier version of it: nvim-peekup (neovim only) :p

You can now opt out of the delay. Credits to u/mfontani for this and other features!

This is how (with a little self-promotion of my plugin) :p
