If you dock the formula editor to the bottom of the window, resize it by hovering your cursor over the top of the editor, then drag the blue line up or down.

If you dock the formula editor to the right of the window, resize it by hovering your cursor over the side of the editor, then drag the blue line from side to side.

Syntax checking applies automatically to your formula. If your formula contains a syntax error, a warning displays in the bottom-right of the formula editor.

The error itself displays inline with the formula as a red underline. To learn about the error, hover over it. A  message explains the error and suggests a course of action.

Only one error displays at a time. Once you correct the first issue, others may display.

When you edit a formula in the expanded formula editor, autocomplete displays suggestions for the text you type. Smart formatting automatically fixes common typos and layout of formulas.

Suggestions display in the order: functions, modules, line items, lists, and list properties.

Formula autocomplete suggests:

• A single-quote ', autocomplete displays modules in the current model.
• Period. after a module name, autocomplete displays line items in the module.

To search all references, press Ctrl + Shift + F (Windows) or Command + Shift + F (Mac).

If you press Escape, autocomplete hides suggestions until you type more.

Smart formatting corrects:

• Indents in conditional logic.
• Formula spacing.
• The formatting of pasted logic, to fit into the formula structure.

You can manage Formula autocomplete and Smart formatting in the formula editor Preferences .
