Dialog radio button field

Radio button fields are used to select a single item from a list
of available options. This is how you handle them:

	Click the radio button of the option you want to activate and all other options will be deactivated automatically. As you select options, the text in the edit box will change to reflect your choice.
	The edit box displays an abbreviation that indicates the currently selected option. The abbreviations are the same as those you would use to specify options in a macro. You can make selections by directly editing the text in the edit box and the status of the radio buttons will change accordingly. The abbreviation displayed in the edit box will be added to the top of the history list when you press Ok to execute the command.
	Use the down arrow button to open the field's drop down history list and reuse one of your most recently specified options.
