The glossary explains words and terms introduced in the documentation.

• Clearing – With clearing, removing of all graphic objects under text is meant, so that the text is easy to read. In practice the clearing takes place by distancing text and printing a white surface before printing the text.
• Data button – The mouse button that is connected with the data point function. For righthanders this is the left mouse button.
• Left-handed people can switch this data function to the right mouse button.
• Hydraulic pressure – Is the manometric pressure plus the static pressure of the medium. Calculation formula see Formula (20.40).
• Hydraulic pressure height – Is the manometric pressure plus the static pressure of the medium. Calculation formula see Formula (20.40).
• Panning – Changing the window selection by moving the mouse. If Ctrl+data button is pressed in a viewport and the cursor moved in the desired direction with the data button held down (Ctrl key can be released), the design detail under the mouse moves. The further the cursor moves from the initial click position, the faster the design under the cursor moves.
• Reset key – The mouse button which is connected to the Reset function. For right-handers this is the right mouse button.
• Left-handed people can switch this data function to the left mouse button.
• Snap distance – Range around the cursor in which a graphical element is searched for when the data button is clicked. If an item is situated within this search radius, it is "captured".
• The snap distance set to 10 pixels as standard and is represented as a circle around the cursor.
• Tentative button – The mouse button which is connected with the tentative function. With 3 button mice this is usually the middle mouse button. MicroStation sets the key combination "left + right mouse buttons" as standard.
• With the tentative function you set a preselection for the next graphical element (options for this through the snap function modes). This preselection must be confirmed with the data key.
• Toolbox – Synonymous for tool box (the English-language version).
• Toolbox – Dialog mask with symbols for the manipulation of the graphic. Tool boxes have the feature that they can be attached to the frame of the window. In this mode the dialog title disappears to save space in favor of the diagram.
