If you want a particular message to have bold text, italic, underline or any other style combination, then you specify the global variable NMGLO:Style with the sum of desired styles before calling the Message() function. For example, like this:
NMGLO:Style = FONT:Bold
Message('What are you waiting for?|Buy me now!||(This message is bold)','Act now')
Will show as:
You can combine styles adding them, like:
NMGLO:Style = FONT:Bold + FONT:Italic
NMGLO:Align = 'C' !Centered
Message('What are you waiting for?|Buy me now!||(This message is bold, italic and auto-centered)','Title')
Will show as:
This is the list of available (and combinable) styles:
FONT:thin, FONT:regular, FONT:bold, FONT:italic, FONT:underline and FONT:strikeout.
Old (version 1.x) method:
If you want a particular message to have bold text, then you can add the keyword @b@ at the beginning of your message. For example, the message
Message('@b@What are you waiting for?|Buy me now!||(This message is bold)','Act now')
Will show the same as the first picture above. Note that the old method only allowed to use the bold attribute.
