The extension offers a range of useful shortcuts to improve navigation and gameplay on OGS. For example, pressing Ctrl + \ enables or disables the entire extension, while Ctrl + m toggles the chat input box on a game page. Additionally, players can use Ctrl + b to toggle the canvas overlay with the stone marker and Ctrl + ] to toggle the arrow keys.

Moving the stone marker is made easy with the use of the arrow keys or the W, A, S, and D keys. Pressing Enter or F will click on the stone marker's location, allowing players to make their moves quickly and efficiently.

OGS Kbd Nav also provides shortcuts for other useful features, such as passing (Ctrl + [), toggling AI analysis (Ctrl + ;), cycling through different board sizes (Ctrl + ,), and toggling the coordinates input field (Ctrl + .).

Please note that this extension currently requires all coordinates to be turned on in order to function properly.

Overall, OGS Kbd Nav is a valuable add-on for Go enthusiasts who want to enhance their online Go experience by utilizing keyboard navigation and accessing handy shortcuts. To learn more about this extension, visit the developer's homepage on GitHub or check out their post on their website.
