Book Writer is an editor and writing environment for creative writers. To give the writer a central hold on a project of multiple chapters, Book Writer provides a Project Manager and a Project Commander. With these, the project is more like a book or manuscript held in the hand than a number of files scattered in the dark of electronic space. Book Writer provides visual interfaces to manipulate a project's files by dragging or clicking book and chapter icons. Book Writer can copy, move, and zip all or selected files in the project all at once. Book Writer can search all files in a project, replace text in all project files, index the project for instant text retrieval, and move from file to file to show the findings. Advanced search features include four ways to search files: plain-text search, regular expressions, approximate, and sound-alike. Find words even if they are misspelled. Instantly find all the lines in your project where you mentioned a particular name, or any word, and move from file to file, line to line by clicking on search results. Book Writer can organize and search the support files for a project, such as research documents or previous works. Just add such files to the project during development, remove later. After indexing, search all your support files instantly. You can use Book Writer's editor and other features without using the Project Manager and Commander. Book Writer omits word processing features for business that are unnecessary for creative writing, such as mail merge and team development. Book Writer includes a complete dictionary and thesaurus with both US and UK English. Turn Active Thesaurus(tm) on and double click any word to see dictionary and thesaurus listings. Book Writer can check spelling as you type. The spell checker can use US or UK English. The program provides pop-up, context-sensitive help via the F1 key. For writers, teachers, and students.
