This command locks all fields, then changes the font of the next field you click on to the 36-point SmartBig font. This font is built into every SmartSlides lecture, so it is always available to you in SmartSlides. There is no separate button for invoking this command, but you can use the OTHER FONT… command, for which there is a button, to do the same job. If, after choosing this command, and before clicking on a field to change its font, you change your mind and do not wish to change the font in any field after all, then simply invoke some other command, or go to another card using the navigation arrow buttons at the bottom of the slide. Either of these actions will cancel the previous command. Of course you can always change the font back again using OTHER FONT….
