In order to easily modify system parameters in large systems (e.g. for sensitivity analysis), parameter values can be changed for multiple components at once.:

• using 'Alt+Cick' within one canvas
• using 'Shift+Alt+Click' to span multiple canvasses

Using 'Alt+Click' within one canvas

When pressing the 'Alt' button while clicking on a basic circuit, all  (or pipe), all basic ciricuits of the same type will be selected at once. The number of selected basic ciruits is shown at the top of the parameter box. Uniform parameters (parameter values are the same for all basic circuits in the selection) are marked in black whereas a red marked parameter value indicates that different parameter values are applied within the selection. When overwriting a red parameter value, the new parameter value will be marked in black which means that it is a now a uniform parameter value.
