# XCUIElement.KeyModifierFlags

Flags for simulating combination keystrokes with keys, such as Control, Option, Shift, and Command.

## Declaration

```swift
struct KeyModifierFlags
```

## Overview

Overview Use these flags with the typeKey(_:modifierFlags:) and perform(withKeyModifiers:block:) methods to simulate combination keystrokes while an action occurs.
