+General filter help
+
+Filters are made of a series of matching terms. E.g. a filter such as:
+
+  Draw Clear Copy
+
+would match each string against event names, and include any event that matches
+any of the above.
+
+You can also exclude matches with - such as:
+
+  Draw Clear Copy -Depth
+
+which will match as in the first example, except exclude any events that match
+'Depth'.
+
+You can also require matches, which overrides any optional matches:
+
+  +Draw +Indexed -Instanced
+
+which will match only events which match Draw and match Indexed but don't match
+Instanced. In this case adding a term with no + or - prefix will be ignored,
+since an event will be excluded if it doesn't match all the +required terms
+anyway.
+
+Finally you can use filter functions for more advanced matching than just
+strings. These are documented on the left here, but for example
+
+  $draw(numIndices > 1000) Indexed
+
+will include any drawcall that matches 'Indexed' as a plain string match, and
+also renders more than 1000 indices.
