 To disable direct chat control (with no prefix), turn off the `chatControl` setting. To disable chat control with the `#` prefix, turn off the `prefixControl` setting. In Impact, `.b` cannot be disabled. Be careful that you don't leave yourself with all control methods disabled (if you do, reset your settings by deleting the file `minecraft/baritone/settings.txt` and relaunching).

+`help`
 
 To toggle a boolean setting, just say its name in chat (for example saying `allowBreak` toggles whether Baritone will consider breaking blocks). For a numeric setting, say its name then the new value (like `primaryTimeoutMS 250`). It's case insensitive. To reset a setting to its default value, say `acceptableThrowawayItems reset`. To reset all settings, say `reset`. To see all settings that have been modified from their default values, say `modified`.
 
@@ -24,13 +40,13 @@ Some common examples:
 - `goal clear` to clear the goal
 - `cancel` or `stop` to stop everything
 - `goto portal` or `goto ender_chest` or `goto block_type` to go to a block. (in Impact, `.goto` is an alias for `.b goto` for the most part)
-- `mine diamond_ore` to mine diamond ore (turn on the setting `legitMine` to only mine ores that it can actually see. It will explore randomly around y=11 until it finds them.)
-- `click` to click your destination on the screen. Right click path to on top of the block, left click to path into it (either at foot level or eye level), and left click and drag to clear all blocks from an area.
-- `follow playerName` to follow a player. `followplayers` to follow any players in range (combine with Kill Aura for a fun time). `followentities` to follow any entities. `followentity pig` to follow entities of a specific type.
-- `save waypointName` to save a waypoint. `goto waypointName` to go to it.
-- `build` to build a schematic. `build blah` will load `schematics/blah.schematic` and build it with the origin being your player feet. `build blah x y z` to set the origin. Any of those can be relative to your player (`~ 69 ~-420` would build at x=player x, y=69, z=player z-420).
+- `mine diamond_ore iron_ore` to mine diamond ore or iron ore (turn on the setting `legitMine` to only mine ores that it can actually see. It will explore randomly around y=11 until it finds them.) An amount of blocks can also be specified, for example, `mine 64 diamond_ore`.
+- `click` to click your destination on the screen. Right click path to on top of the block, left click to path into it (either at foot level or eye level), and left click and drag to select an area (`#help sel` to see what you can do with that selection).
+- `follow player playerName` to follow a player. `follow players` to follow any players in range (combine with Kill Aura for a fun time). `follow entities` to follow any entities. `follow entity pig` to follow entities of a specific type.
+- `wp` for waypoints. A "tag" is like "home" (created automatically on right clicking a bed) or "death" (created automatically on death) or "user" (has to be created manually). So you might want `#wp save user coolbiome`, then to set the goal `#wp goal coolbiome` then `#path` to path to it. For death, `#wp goal death` will list waypoints under the "death" tag (remember stuff is clickable!)
+- `build` to build a schematic. `build blah.schematic` will load `schematics/blah.schematic` and build it with the origin being your player feet. `build blah.schematic x y z` to set the origin. Any of those can be relative to your player (`~ 69 ~-420` would build at x=player x, y=69, z=player z-420).
 - `schematica` to build the schematic that is currently open in schematica
-- `tunnel` to dig just straight ahead and make a tunnel
+- `tunnel` to dig and make a tunnel, 1x2. It will only deviate from the straight line if necessary such as to avoid lava. For a dumber tunnel that is really just cleararea, you can `tunnel 3 2 100`, to clear an area 3 high, 2 wide, and 100 deep.
 - `farm` to automatically harvest, replant, or bone meal crops
 - `axis` to go to an axis or diagonal axis at y=120 (`axisHeight` is a configurable setting, defaults to 120).
 - `explore x z` to explore the world from the origin of x,z. Leave out x and z to default to player feet. This will continually path towards the closest chunk to the origin that it's never seen before. `explorefilter filter.json` with optional invert can be used to load in a list of chunks to load.

+/**
+ * The {@link IArgConsumer} is how {@link ICommand}s read the arguments passed to them. This class has many benefits:
+ *
+ * <ul>
+ * <li>Mutability. The whole concept of the {@link IArgConsumer}} is to let you gradually consume arguments in any way
+ * you'd like. You can change your consumption based on earlier arguments, for subcommands for example.</li>
+ * <li>You don't need to keep track of your consumption. The {@link IArgConsumer}} keeps track of the arguments you
+ * consume so that it can throw detailed exceptions whenever something is out of the ordinary. Additionally, if you
+ * need to retrieve an argument after you've already consumed it - look no further than {@link #consumed()}!</li>
+ * <li>Easy retrieval of many different types. If you need to retrieve an instance of an int or float for example,
+ * look no further than {@link #getAs(Class)}. If you need a more powerful way of retrieving data, try out the many
+ * {@code getDatatype...} methods.</li>
+ * <li>It's very easy to throw detailed exceptions. The {@link IArgConsumer}} has many different methods that can
+ * enforce the number of arguments, the type of arguments, and more, throwing different types of
+ * {@link CommandException}s if something seems off. You're recommended to do all validation and store all needed
+ * data in variables BEFORE logging any data to chat via {@link Helper#logDirect(String)}, so that the error
+ * handlers can do their job and log the error to chat.</li>

+ * <ul>
+ * <li>Create a new instance with the empty constructor</li>
+ * <li>Use {@code append}, {@code prepend} or {@code add<something>} methods to add completions</li>
+ * <li>Sort using {@link #sort(Comparator)} or {@link #sortAlphabetically()} and then filter by prefix using
+ * {@link #filterPrefix(String)}</li>
+ * <li>Get the stream using {@link #stream()}</li>
+ * <li>Pass it up to whatever's calling your tab complete function (i.e.
+ * {@link ICommandManager#tabComplete(String)} or {@link IArgConsumer}#tabCompleteDatatype(IDatatype)})</li>
+ * </ul>
+ * <p>
+ * For advanced users: if you're intercepting {@link TabCompleteEvent}s directly, use {@link #build()} instead for an
