Question: I am implementing a CDS system, and I would like to use the **DataRequirement** type to ask for additional information. However, I am having some difficulties to understand the **filter elements** ("codeFilter" and "dateFilter"). 

For example, the property "**path**" of the filter elements is of string type, but what is the format to specify this path?
I have been searching some examples from the FHIR specification, and I've tried to follow the "path" in the resource object. I attach below an image with an example and the specification of the resource "MedicationRequest" that is being addressed in this example. Can anyone explain me over this example how to traverse throw the elements? What is the element "code" from the path refering to?

[example DataRequirement.codeFilter](https://i.stack.imgur.com/gGnMr.jpg)

Can anyone help me with this issue? Examples of use would be appreciated!

Thanks in advance.

Answer: 
**Outdated**

For IntelliJ 2017.1.2, to resize a Tool window, hold `Ctlr`-`Shift` and use the arrow keys to either shrink or expand the window.

**Update for IntelliJ 2022.2**

macOS:

* To resize a vertical tool window, press `⌃ ⌥ ←` and `⌃ ⌥ →`
* To resize a horizontal tool window, press `⌃ ⌥ ↑` and `⌃ ⌥ ↓`

Windows:

* To resize a vertical tool window, press `Ctrl+Alt+Shift+Left` and `Ctrl+Alt+Shift+Right`
* To resize a horizontal tool window, press `Ctrl+Alt+Shift+Up` and `Ctrl+Alt+Shift+Down`

This is an update as Luciano's answer does not work for me: on 2021.2.2, in the windows keymap, the default is `Ctrl`+ `Alt` + `Shift` + `arrowKey`. You can also change it there.
