Once you have created the tool set, start filling it up with markups. Click Manage Tool Sets at the top of the Tool Chest tab.Custom markups can be saved in the pre-created “My Tools” tool set, or in your own custom tool set. Revu comes with a number of useful tool sets, or collections of markups, in the Tool Chest, but you can also create and share your own tool sets full of customized markups and measurements that fit exactly what you need and how you work. For example, while the Highlight button on the toolbar allows you to save one default appearance for the Highlight tool, the Tool Chest can store multiple color and thickness combinations that you can access with a single click. The Tool Chest is a place where you can store customized markups so you can quickly add them to your PDFs without having to recreate them.
