You're absolutely correct! Thank you so much for this issue!

Hey! @lucasoares What version / commit of huh? are you on. I can't reproduce with a simple example. Can you share the code that you're using:

The first time I execute the form:

Then if I move my selection the help text changes:

Also, if I press tab in the first option, it confirms the selection, but only enter should do it.

If I press any key when I'm in the first option, the help text changes too, and tab key will not confirm anymore. The following example I executed the form, pressed x and then tried to press tab

Code example:

// Helper functions to create form

func NewForm(groups ...*huh.Group) *huh.Form {
    return ConfigureForm(huh.NewForm(groups...))
}

func ConfigureForm(form *huh.Form) *huh,Form {
    keymaps := huh.NewDefaultKeyMap()
    keymaps.Quit = key.NewBinding(key.WithKeys("ctrl+c", "esc"))
    keymaps.Select.SetFilter = key.NewBinding(key.WithKeys("'"), key.WithHelp("'", "set filter"), key.WithDisabled())
    keymaps.Select.ClearFilter = key.NewBinding(key.WithKeys("'"), key.WithHelp("'", "clear filter"), key.WithDisabled())
    keymaps.MultiSelect.SetFilter = key.NewBinding(key.WithKeys("enter", "'"), key.WithHelp("'", "set filter"), key.WithDisabled())
    keymaps.MultiSelect.ClearFilter = key.NewBinding(key.WithKeys("'"), key.WithHelp("'", "clear filter"), key.WithDisabled())

    huhForm := form.WithKeyMap(keymaps)

    return form: huhForm
}

And using it:

    form := NewForm(
        huh.NewGroup(
            huh.NewSelect[string]().
                Title(title).
                Description(description).
                Options(menuOptions...).
                Value(&selected),
        ),
    )

    err := form.Run()

This simple example with single item in a single group form will have these issues I mentioned.

Hey, we fixed this on main! We will do a release soon!

The problem was setting the keymaps and that was fixed in https://github.com/charmbracelet/huh/commit/8c5d66193f2b83a5b6ff2443dec16964d7fe2bb7
