It was originally developed for the authors personal use, but it has been cleaned up and packaged as a set of button strips for anyone with final writer to use.
The macros are attached to button strips, which allow you to click and add the html text as you type. Also included is a use pull down menu, which allows you to activated the macros by using the function keys on the keyboard. This makes it easy to get the code you need without going near the mouse, for those of you who hate trying to use final writer with silicon menus ... :) but, thats another story - see comp.sys.amiga.applications
