How to make 'tab' choose a completion when it is the only one

[ittaysw]

Without fzf-tab, If I have a prefix with several completions and hit tab, they are shown. If I then add a few characters and hit tab, and there is now only one completion, it is completed.
With fzf-tab when there are several completions, they are shown. If I then add some search term so that the list is narrowed to one and hit tab, nothing happens. I need to hit enter.
I would like to have tab enter the selection (when there's a single one or many). Right now it is bound to 'down'

You can bind tab to accept:

zstyle ':fzf-tab:*' fzf-bindings 'tab:accept'

But it'll always happen (not only if you have a single result)

noob here. where does this line go? in my zshrc file? or is there a separate place for fzf-tab configuration?

This depends on when fzf supports dynamic binding. Currently, you cannot change the binding at runtime.
