Perform type inference on any expression in your program.
Sometimes you have a complex Elm expression and you want to know what the type of part of it is. With this feature you can select a sub-expression and ask IntelliJ to compute its type.
This feature operates automatically in the background, and increases RAM and CPU usage proportionally to the size of your codebase (and dependencies).
Press Ctrl-Shift-P to see the type of the expression under the cursor, or expand the selection to include parent expressions.
