You can specify the font in the text statement. For example, the statement:
font "esl mono" text "Mono Font"
displays the string, "Mono Font", in the esl mono font. If no font is specified, the text is displayed in the font currently in effect.
You can also specify the color in which the text string is to be displayed; for example:
key Select...
red font "esl mono" text "Hello"
