Among the objects that can be created from a script are hotwords, essential to any serious hypermedia application. Many of our users want to (for example) open a text file, read it into fields, search for certain words or phrases, and create links to other pages. This is complicated by problems in "finding" hotwords immediately after their creation. The purpose of this book is to provide working examples of dynamic creation of hotwords in each of the three types of fields in Toolbook. In order to understand the care and feeding of hotword objects, we need to understand the nature of their habitat, the Toolbook field. There are three types of Toolbook field: foreground, background, and record fields. Toolbook field objects(taken together) have one great strength and one great weakness. Their strength lies in the fact that the field types have unique features, and can complement their cousins if used right. Their weakness lies in the fact each each field type has unique features, and must be handled in a unique manner. The principal difference between field types is the location of their text. The text in a background field lives in the background with the field. This is useful for header lines and titles where the text does not change from page to page; for example, the title "The Hotword Book" at the top of this page is in a background field. The text of record fields, on the other hand, lives in the foreground, while the recordfield itself lives on the background. This is useful for preparing blank forms, where the overall format is the same on each page, but the text entered on each page will change. Problems arise when users look for hotwords in the wrong place. This is compounded by the fact that some hotwords "move" as they are created, so they cannot be found in the same place as their text! This book is organized along the lines of field types -one page, one field type. This is no accident. Each page contains a valid reference to a hotword of that field type. ick cribsheet, look at the "HotHandle" field on each page. e you have a handle on the hotwords, you have several tools available for accessing them.

Here the text is selected through a search, checked to see if it is already a hotword, and a hotword is created if one does not already exist. The newly minted hotword is named immediately after its creation. The hotword is an object of the recordfield, whether it is addressed by name or simply as objects of a specific recordfield. For example, if the hotword was named "Barney" and the recordfield was named "Rubble" the hotword could be found as any one of: objects of recordfield Rubble or hotword Barney of this page.or hotword Barney ofage, The Hotword Book backField1 This is background field BackField1.

The hotwords are objects of the field immediately after they are created. Foreground fields are the easiest fields to handle, and should be the starting point for a beginner. As always, you must start the creation process by selecting the text you will turn into a hotword. In these scripts, this is done by executing a search for the text. The selectedText is then the target for the message "CreateHotword". It is always a good idea to set the name of the object immediately after its creation. In order to do so, one must first get a valid handle to the new hotword, often trickiest part of the process. In this case, the expression "objects of the field" will return a comma separated list of the objects of the field, all of which should be hotwords. Just the same, the script uses the contains operator to test that condition. The last hotword in the field will be the last object in the list. Knowing this is essential to naming the hotwords. After naming, the hotword is a hotword of the field, in addition to being an object of the page. A hotword named "Fred" in field "Flintstone" can be found as hotword Fred of field Flintstone. Since this is not the case for all types of fields, you need to be sure you know which type of field you are dealing with before you start.

The text is in the background, and the hotwords can be found only as objects of the field of the background. It is important to remember that you need to be on the background when you select the text in a background field. If you do not do this, you are inviting trouble! Remember, always execute send author; send background before you create a hotword on the background! word on the background!
