Confirm returns the same IKeyPressControl as KeyPress, so it exposes the identical fluent API. Rather than duplicate it here, this page summarises the methods and links to the full reference on the KeyPress → Methods page.

The factory is PromptPlus.Controls.Confirm(string prompt = "", string? description = null, bool showresult = false), which returns IKeyPressControl. It differs from KeyPress(...) only in that the culture Yes/No keys are pre-registered as valid keys.

The factory parameters

IKeyPressControl Confirm(string prompt = "", string? description = null, bool showresult = false)

Parameter	Meaning
prompt	The prompt text shown to the user. Default empty.
description	An optional description line shown under the prompt. Default null.
showresult	When true, the answer line stays on screen after the control finishes; when false (default) it is hidden after finish.

PromptPlus.Controls.Confirm("Apply changes", "Press Y or N").Run();

The shared API

Method	Purpose	Full reference
AddValidKey	Register an additional valid key (accumulates on top of the pre-set Yes/No keys)	KeyPress → AddValidKey
ShowMessage	Message shown for a rejected key	KeyPress → ShowMessage
ShowMessageAsync	Async message for a rejected key	KeyPress → ShowMessageAsync
Styles	Recolor a KeyPressStyles region	KeyPress → Styles
Options	Per-control behavior overrides	KeyPress → Options
Run	Display and return ResultPrompt<ConsoleKeyInfo?>	KeyPress → Run

Because Confirm already registers the Yes/No keys, calling AddValidKey adds more accepted keys — it does not replace the yes/no pair. For a plain yes/no question you normally call none of these except optionally Options, Styles, and Run.

---

Typical Confirm chain

using PromptPlusLibrary;

var confirm = PromptPlus.Controls
    .Confirm("Delete file?")
    .Options(o => o.ShowTooltip(true))
    .Run();

Reading the result (yes/no) is covered on the Index page.
