The Expression Assist is a utility feature that provides
a quick way to enter expressions in the Expression text field by opening
a scrollable list of available options.
Following are a few tips on how to use the Expression
Assist:
You can use the mouse or the keyboard
to navigate and select a line in the list of options. Click or press
Enter to insert the selected expression into the text field.
The list of options opens when the cursor
is placed at a location where expression completion makes sense, for
example, after a separator.
The proposed expression options are
syntactically correct, but might not be semantically correct.
The list of expression options displays
the expression options followed by a short description of the options.
Example:
Create a new diagram by clicking File
> New.
In the diagram window, click one of the blue boxes.
In the Styling Customizer, at the right of the name field, type +.
The Expression Assist displays the list of expression
options. First in line are the model attributes, followed by the variables,
then the functions.
