NVDA's settings dialog is divided into categories. The user guide covers these in section 12: https://www.nvaccess.org/files/nvda/documentation/userGuide.html#NVDASettings

In 12.1, the guide mentions there are shortcut keys to jump to specific categories and also talks about changing categories. It would be worth including a sentence clarifying that you can change categories with control+tab / control+shift+tab.

Describe the solution you'd like

The last line before of 12.1 reads:
The settings categories found in the NVDA Settings dialog will be outlined below.

A sentence could be added after this reading:

To change between categories, press control+tab to move forward, or control+shift+tab to move backwards, or use tab or shift+tab to move to "Categories" list and use the arrow keys.

Describe alternatives you've considered

Although these are standard Windows controls, and thus not otherwise covered in the user guide, as it covers navigating a specific dialog within NVDA, it doesn't hurt to confirm this is how the dialog works as there can be alternate implementations of similar controls. We have recieved a query from a user on this.

(These keys are currently covered in the Basic Training for NVDA module as well, though not in the context of the NVDA settings dialog).
