The **Tools** group allows manipulating and editing content in the [C1RichTextBox](/componentone/api/wpf/online-richtextbox/dotnet-api/C1.WPF.RichTextBox/C1.WPF.RichTextBox.C1RichTextBox.html) control. The Tools group appears similar to the following image:

The **Tools** group includes the following options:

*   **Spell Check**: Clicking the **Spell Check** button opens the **Spelling** dialog box. Note that spell-checking must be set up for this button to be active. See [Spell-Checking](/componentone/docs/wpf/online-richtextbox/Working_with_RichTextBox_for_WPF/spell-checking) for details. In the **Spelling** dialog box you can view suggested spellings and **Ignore** the error, **Ignore All** errors in instances of the same word, **Change** the current spelling to a suggested one, **Change All** instances of the current spelling, **Add** the current spelling to the spell-checking dictionary, **Suggest** to view additional spellings based on a suggested spelling, and **Cancel** to close the dialog box and cancel the spell-check operation.

*   **Find and Replace**: Clicking the **Find and Replace** option displays a drop-down box that allows you to enter text to find or find and replace in the content of the RichTextBox. You can **Replace** each instance one by one, **Replace All** instances, or **Find Next** instance.
