The font style of tasks or resources can be changed either by using the “Text Styles” option from the “Format” menu or the “Font control” option from the “Task” menu. By using the “Text Styles” option, the style for a category of tasks (summary, milestones, etc.) or resources (highlighted, overallocated) can be changed at the same time. By using the “Font control” option, the changes will be applied only to the selected task or resource from the grid.
