Describe the question

How exactly does this option work?
I've watched the video about this, but I don't understand how the spottter comes up when you hit enter on a library when searching. I'm already using the default keymap and yazi.toml files, but still the spotter doesn't come up for me.

Anything else?

It's <Tab> by default, not <Enter>

"Every time a user clicks <Tab> on a directory, the latest size is calculated."
