So you should aim to capture any regularly used tags in the list above. Also note that some tags are explicitly excluded using the //ignore// field. You might find you want some of these eg ele(vation) and you should remove any such tags that you want.

+Once you have set up the connection, you can extract data using (for example) the Processing Toolbox->Vector Overlay->Extract/clip by extent. Select one of the layers within the file (points, lines, multipolygons) as the Input Layer, and select an area to load - by map or by file. Be careful not to make it too large, or you'll get very slow performance.
 ====== Style data in QGIS ======
+Here are some sample bushwalking-based style files for OSM points and OSM lines:
+  * {{ :osm_bw_points.qml |OSM Points}}
+  * {{ :osm_bw_lines.qml |OSM Lines}}
+Note that they will only work fully if you have matched the tags that I'm importing.
+That said, you can generally fix any issues relating to tags by replacing a basic filtering rule such as
+''"natural"='peak'''
+with
+''hstore_to_map(other_tags)['natural'] = 'peak'''
