Adding fn.complete_and_next_item

[beshoux]

When you use the regular cmdline of nvim, when you press Tab it shows you the completion menu + selects the next item at the same time, While right now with the current Fine-CmdLine we have to press the Tab once to show the completion menu then we have to press it again to make it start selecting entries from the completion

So I suggest a new function called fn.complete_and_next_item that would show the menu and directly choose the next item without having to press Tab again.

Behaviour on the menu depends on completeopt. With set completeopt=menu,menuone it should do what you want. Or actually, just removing noselect from the list works fine.

Indeed that worked, thank you. This issue shall be closed now.
