    Expression field
    Edit your expressions in the expression field (1). Use Ctrl+Space to autocomplete a word or show a list of suggestions.
    Most of the buttons in the toolbar (2) are the operators developers use often. Click the button to insert the element in the expression field.
    Scope pane
    The scope pane (3) shows the elements you can use in the expression, like variables, built-in functions, scripts. The availability of local elements depends on where in the app you're editing the expression. Note that only actions that you set as functions show in the scope pane.
    Description pane
    You can read the details about an element in the description pane (4). If a function has documentation, the documentation shows in the description pane.
    The expression status (5) tells you if the expression you're editing is valid or not.
