Design Guidelines
Display All Pushbuttons
Try to display all the pushbuttons that are important for a task (approx. 6 - 7). Use appropriate abbreviations, to fit them all in the toolbar (see
Abbreviations).
Since some general functions are implemented in the standard toolbar, you can accomodate more functions in the application toolbar. Standard toolbar functions are not discussed further in this section (see
Consistent Terminology
Always use the same terms and abbreviations for the same function in your task (see
Formulations and Functions - Overview).Standard Functions
You can display those standard functions
F2= Choose, F13= Print and F14=Delete which are active.You can also display other standard functions in the application toolbar. This includes the
Hold, Save without check and Sort functions which are assigned to general function keys.Do Not Display
the
F9=SELECT (if defined with Select/Deselect (Function)) and F10=MENU BAR pushbuttons (see Menu Bar (Function)).Justification: It does not make sense to define pushbuttons for these functions because it is easier to click directly on the specified object.
Self-Defined Function Keys
The self-defined function keys (always define
F5-F8 first) should be displayed as pushbuttons if possible. At least the most frequently used functions should always be implemented as pushbuttons.Justification: These pushbuttons cover specific, self-defined functions, which are difficult to learn and to remember.
Additional Navigation Functions
If the navigation keys are used for moving between the task hierarchy levels (
F17-F20 ), they can be displayed.Grouping Pushbuttons
Group pushbuttons in the following order:
Within these three groups, the pushbuttons are to be arranged in ascending order of the corresponding function keys.
In dialogboxes,
