Auto-fzf on ambiguity without relying on tab completion?

[rieje]

I like zoxide but want to use it without ambiguity, is the following possible?

z down<Enter> either shows completion if there's more than one directory with suffix "down" in the name, e.g. ~/downloads, /tmp/downloads, or just jumps to it. I don't want to 1) hit enter and potentially jump into the wrong directory, and 2) explicitly <space>Tab for completions because that assumes I know I have more than one directory with the same name.

P.S. Is it possible to give nicknames of similarly named directories for faster matching? E.g. for /usr/bin, ~/bin, ~/.local/share/bin, give nicknames ub for /usr/bin and lsb for ~/.local/share/bin after completing for z bin and then you don't need to type e.g. l s b with the spaces for ~/.local/share/bin.
