Escaping special characters in Windows International Keyboard

The Windows International Keyboard allows you to enter letters with accent marks. For example, to type é, just type Apostrophe e. But what if you just want to enter (or escape) an apostrophe (for example, when entering a string literal while programming)? The trick is to type a space after the apostrophe, as per this bullet point in the support page: If you press the space bar, the symbol (apostrophe, quotation mark, accent grave, tilde, accent circumflex or caret) is displayed by itself.
