+angles in radians.
+
+* `vector.rotate(v, r)`:
+ * Applies the rotation `r` to `v` and returns the result.
+ * `vector.rotate({x = 0, y = 0, z = 1}, r)` and

+ forward and up relative to an entity's rotation `r`.
+* `vector.rotate_around_axis(v1, v2, a)`:
+ * Returns `v1` rotated around axis `v2` by `a` radians according to
+ the right hand rule.
+* `vector.dir_to_rotation(direction[, up])`:
+ * Returns a rotation vector for `direction` pointing forward using `up`
+ as the up vector.
+ * If `up` is omitted, the roll of the returned vector defaults to zero.
+ * Otherwise `direction` and `up` need to be vectors in a 90 degree angle to each other.

* a button was pressed,
* Enter was pressed while the focus was on a text field

text as value. If not pressed, is `nil`
* `field`, `textarea` and variants: Text in the field
- * `dropdown`: Text of selected item
+ * `dropdown`: Either the index or value, depending on the `index event`
+ dropdown argument.
* `tabheader`: Tab index, starting with `"1"` (only if tab changed)
* `checkbox`: `"true"` if checked, `"false"` if unchecked
* `textlist`: See `minetest.explode_textlist_event`
* `nodenames`: e.g. `{"ignore", "group:tree"}` or `"default:dirt"`
* `search_center` is an optional boolean (default: `false`)
If true `pos` is also checked for the nodes
-* `minetest.find_nodes_in_area(pos1, pos2, nodenames)`: returns a list of
- positions.
+* `minetest.find_nodes_in_area(pos1, pos2, nodenames, [grouped])`
+ * `pos1` and `pos2` are the min and max positions of the area to search.
* `nodenames`: e.g. `{"ignore", "group:tree"}` or `"default:dirt"`
- * First return value: Table with all node positions
- * Second return value: Table with the count of each node with the node name
- as index.
+ * If `grouped` is true the return value is a table indexed by node name
+ which contains lists of positions.
+ * If `grouped` is false or absent the return values are as follows:
+ first value: Table with all node positions
+ second value: Table with the count of each node with the node name
+ as index
* Area volume is limited to 4,096,000 nodes
* `minetest.find_nodes_in_area_under_air(pos1, pos2, nodenames)`: returns a
list of positions.
* Returns a code (0: successful, 1: no such player, 2: player is connected)
* `minetest.remove_player_auth(name)`: remove player authentication data
* Returns boolean indicating success (false if player nonexistant)
+* `minetest.dynamic_add_media(filepath)`
+ * Adds the file at the given path to the media sent to clients by the server
+ on startup and also pushes this file to already connected clients.
+ The file must be a supported image, sound or model format. It must not be
+ modified, deleted, moved or renamed after calling this function.
+ The list of dynamically added media is not persisted.
+ * Returns boolean indicating success (duplicate files count as error)
+ * The media will be ready to use (in e.g. entity textures, sound_play)
+ immediately after calling this function.
+ Old clients that lack support for this feature will not see the media
+ unless they reconnect to the server.
+ * Since media transferred this way does not use client caching or HTTP
+ transfers, dynamic media should not be used with big files or performance
+ will suffer.
