The task bar allows rapid one-click access to the standard operations of creating a new document, opening, saving or printing the contents of the current file, copying, cutting and pasting text, searching for specific text within the document, and undoing or redoing previous edits.
Two buttons allow insertion of complete text files. One allows the user to select any file from local or network-mounted file systems. The other imports a specific file (the location of which may be specified by the user through the `Preferences…' selection of the main `Edit' menu). While this specific file may contain anything, it is intended to be a template CIF that a user will tailor to meet their own requirements. The default provided with the software is a standard template distributed by the IUCr for use in submitting articles to Acta Crystallographica. In either case, the file is imported at the current editing location and is not subject to validation upon input; the user must manually revalidate the file after import.
An icon on the task bar allows the user to run a validation procedure. This icon will be dimmed (indicating that the validation procedure may not be run) unless the user has modified the contents of the CIF. Other icons on the task bar behave in the same manner, allowing the procedures with which they are associated to be executed only under appropriate circumstances. Thus, for example, the looped list editor is not invoked unless the user clicks within the reserved word loop_ in a list header.
Similarly, the `help' icon in the task bar is dimmed unless the user has selected a data name in the CIF; when this is done, the icon is activated and clicking on it launches a help window containing the CIF dictionary definition of the data item.
The task bar also contains a drop-down menu listing all the data-block names in the current file. When the user selects one of the data-block names, the edit cursor is positioned at the head of the matching data block in the edit window. This is a rapid and efficient way of navigating within large and complex files.
The other buttons provided on the task bar allow the user to: reduce or increase the font size in the editing window; create a new looped list within the loop-editing window; invoke the publication and data-entry wizards; and hide or reveal the dictionary browse window pane.
Users may modify the appearance of the task bar to retain or conceal subsets of these icons, depending on which they find most useful.
