Configuration (zsh) - Aloxaf/fzf-tab GitHub Wiki

As a front end of the zsh compsys, fzf-tab's behavior will also be affected by the configuration of the compsys.

group descriptions

If you configure group description like this zstyle ':completion:*:descriptions' format '[%d]'. fzf-tab will group the results by group description.

[!NOTE] fzf-tab won't do prompt expansion on your description, this is differ from zsh's default behavior

unambiguous prefix

If you set zstyle ':completion:*' menu no, fzf-tab will try to complete unambiguous prefix without user confirmation.
