    These are different audio APIs supported by Windows. They have different characteristics. MME uses the oldest Windows audio API which does not offer good play/record latency. DirectX improves this, but still imposes a penalty of 10s of milliseconds due to the system mixing of streams from multiple applications. WDM-KS avoids the mixing penalty of DirectX, and has very good latency characteristics; better than DIrectX. In general, if you can get WDM-KS to work with your third-party audio application, then you should use it as Mack has indicated. Otherwise try DirectX next and MME last.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
