MemoBox and RichTextMemo
MemoBoxes are multi-line EditBoxes, and RichTextMemos add to this the ability to display a limited subset of text attributes, such as bold, italic, underline, colors and fonts.

The following shortcuts are useful :
•CTRL+B : turns the current selection into bold.
•CTRL+I : turns the current selection into italic.
•CTRL+U : underlines the current selection.
•CTRL+T : strikes out the current selection.
Additionally, all the standard Windows text selection and clipboard keyboard shortcuts are available.
