Cranium's and Synapse's user interface architecture is designed to reuse common themes. Documents form the base of the user interface. Documents are divided into chapters. Chapters are divided into sections. Sections are divided into fields.

Each field contains one or more controls such as labels, datum controls, estimate controls, units controls, tables and graphs. Clicking the left mouse button on these controls typically activates an edit dialog. Clicking the right mouse button on these controls typically activates a commands menu.

• Edit All Data: uses an All Data dialog to enable editing data having status values of passive, rejected or unknown. See documentation for each specific field for details.
• Edit Data: typically activates a property specific edit dialog enabling you to change datum values, graph attributes, state variables, design options, etc. See documentation for each specific field for details. accuracy,
• Compile Values: uses the Compile Property Values dialog to compile data and/or estimates for the current physical property. See Compile Chemical Property Values for documentation on compiling chemical properties and Compile Mixture Property Values for documentation on compiling mixture properties.
• Internet Search: executes the internet search associated with this property on the current entity. See documentation on the Web Search Dialog for details on performing internet searches.
• Copy Special: allows you to choose which attributes of the current datum or estimate should be copied to the Windows clipboard. See Copy Special for documentation.
• Copy Data or Copy Estimate: copies the displayed values to the windows clipboard. Only displayed values are copied, e.g., the datum's value is copied - the reference and comment are not copied.
• Paste Special: allows you to choose which values should be pasted from those on the Windows clipboard. This command is very useful when pasting values copied from spreadsheets and text-based documents. See Paste Special for documentation.
• Paste Data: copies data from the Windows clipboard into this section's data table. Values must be separated by tabs and set of values must be separated by newlines.
• Clear Special: provides the capability of clearing non-required values from each datum.
• Clear All Data: removes all data, e.g., active, passive, rejected, and unknown data, for this property from the current entity.
• Clear Data or Clear Estimate: removes the active data for this property from the current entity.
• Cut Data or Cut Estimate: copies the active data or estimate for this property from the current entity and then clears the data. This command can be thought of as a combination of the Copy Data and Clear Data commands.

• Edit Variables & Detail Estimates: activates the Property Estimates dialog which enables you to view estimation details, enter state variables for new estimations, copy values, regress values and use Goal Seek to find state variables giving specified estimated values. See Estimates Edit Dialog for documentation on these capabilities.
• Select Technique: enables you to specify the estimation mode and the estimation technique used to estimate the current physical property. Selecting this command activates the Estimation Technique Information dialog. The dialog lists two estimation modes: Automatic and Manual. By default all estimations are initially set to Automatic Mode. Once you choose Manual Mode, the list of estimation techniques is enabled allowing you to choose any application estimation technique. See documentation for the Manual Techniques Dialog for more details about manually setting estimation techniques.
• Compile Values: uses the Compile Property Values dialog to compile data and/or estimates for the current physical property. See Compile Chemical Property Values for documentation on compiling chemical properties and Compile Mixture Property Values for documentation on compiling mixture properties.
• Internet Search: executes the internet search associated with this property on the current entity. See documentation on the Web Search Dialog for details on performing internet searches.
• Copy Variables and Estimates: copies the values for all state variables and estimates to the clipboard.
• Copy State Variables: copies the values for all state variables to the clipboard. This command is very useful when estimating several properties over the same range of state variables.
• Copy Special: allows you to choose which attributes of the current datum should be copied to the Windows clipboard. See Copy Special for documentation.
• Paste State Variables: pastes temperature values from the clipboard into the table control. All current values are replaced by the pasted values. If you wish to add new values to the current values, first activate the Estimates Edit dialog (click the left mouse button on the field's table) and then paste the new values in the edit dialog. See Estimates Edit Dialog for additional documentation.
• Paste Special: allows you to choose which values should be pasted from those on the Windows clipboard. This command is very useful when pasting values copied from spreadsheets and text-based documents. See Paste Special for documentation.
• Clear Variables and Estimates: clears all values from the table control. If you wish to clear only selected rows, first edit the current values and then select and clear the desired rows in the edit dialog. See Estimates Dialog for additional documentation.
• Cut Variables and Estimates: copied all values from the table control and then clears all values from the table control. This command can be thought of as a combination of the Copy Variables and Estimates command and the Clear Variables and Estimates command.
• Clear Estimates: clears estimated values from the table control. The state variables are not removed.
• Compute Estimate: activates the Property Estimation dialog which enables you to estimate the current physical property. The functionality of this command is similar to that of the Commands menu Compute Estimates command. The key difference is that the estimates control's menu command limits the estimation to only the current physical property. See Estimate Chemical Properties for documentation.
• Detail Estimate: activates the Details Dialog displaying information about the estimation technique used. See documentation on the Estimate-Units-Technique Dialog for details.

• Insert Symbol: activates the Symbol Dialog enabling you to select mathematical and non-English language symbols for insertion. (See documentation on the Symbol Dialog for details.)
• Change Case: displays a submenu that enables you to change the case of the select text to lowercase, uppercase or title case. See Changing Case for documentation.
