Every menu action has a slash-command equivalent for chat-driven workflows. All commands need OP (permission level 2) — single-player creative already has it. /dt is shorthand for /dungeontrain and both work everywhere.

Key	Action
X	Toggle the command menu.
Z (tap)	Open the block-variant menu against the block you're looking at.
Z (hold) + right-click	Add the held block to that position's variant pool. Empty hand adds an empty-space entry.
C (tap)	Open the container-contents menu against the chest / barrel / hopper / etc you're looking at.
V (tap)	Open the template-blocks menu for the plot you're standing in.

X, Z, C, and V are rebindable under Esc → Options → Controls → Dungeon Train.

Command	What it does
/dt spawn [count]	Spawn a new train with count carriages (default from config).
/dt speed <value>	Set train speed in blocks/second. Persists; any live train updates.
/dt carriages <count>	Change the default carriage count. Live trains resize.
/dt tracks on|off	Toggle whether the bridge auto-generates under the train.

Command	What it does
/dt editor	Enter the editor, teleport to the Carriages plot grid.
/dt editor exit	Exit the editor, return to where you came from.
/dt editor carriages	Switch to the Carriages category.
/dt editor tracks	Switch to the Tracks category.
/dt editor contents	Switch to the Contents category.
/dt editor pillar	Switch to the Pillars subtree.
/dt editor enter <variant>	Teleport directly to the named template's plot.
/dt editor doorghosts on|off	Show or hide the Entrance / Exit door labels on carriage, contents and dimensional-carriage plots. On by default.

Command	What it does
/dt save	Save the plot you're standing in.
/dt save all	Save every plot in the current category, skipping empty ones.
/dt reset	Restore the plot from its last save, discarding unsaved edits.
/dt editor clear	Wipe interior blocks to air without removing the template.
/dt editor observers on|off	Editor Settings → Observers. Off keeps every observer inside an editor plot quiet, hand edits included; saved with the world. Either way the editor's own rewrites (variant previews, resets) never pulse one. See Observers setting.
/dt editor mobs blocks|live	Editor Settings → Mobs. Blocks (default): a spawn egg in an editor plot places a frozen, one-hit mob and variant cells with a mob entry show the mob in the preview cycle; Live is the vanilla egg. Saved with the world. See Mobs setting.
/dt editor unsaved	List every template with unsaved edits and its first differing blocks (expected -> live, or variants -> edited for a variant-pool change) — the same scan behind the pulsing Save icon, in chat and the server log.

Command	What it does
/dt editor new <name> [source]	Create a new template. Source is blank, current, or standard (default: blank).
/dt editor save <new_name>	Rename the current template — or fork it if it's a protected built-in.
/dt editor reset <name>	Remove the named custom template. Built-ins can't be removed.
/dt editor label <id> <name…>	Set the display label the editor shows for a carriage (blank clears). The id and file stay put, so built-ins work too. contents label <id> <name…> for contents.
/dt editor contents group move <child> <new_parent>	Re-parent a contents sub-variant in one step, keeping its weight, gate and Stage links. Lands you in the moved plot.
/dt editor contents reset <id> [all|unparent|promote]	Remove a contents template. A group parent needs the mode word — all deletes the sub-variants too, unparent makes them top-level (weight/gate/first Stage carried), promote hands the group to the first sub-variant — and is refused without one.

Command	What it does
/dt editor mirror x|y|z on|off	Toggle a mirror axis on the plot you're standing in (any category). Edits reflect live across the plot centre.
/dt editor tracks mirror <kind> <name> x|y|z on|off	Toggle a mirror axis on a named track-side template (scripting / out-of-plot).

Off by default everywhere except tunnels (X + Z on). The X → Mirror row has the same toggles. See Templates ▸ Mirroring.

Command	What it does
/dt editor tracks new <kind> <name>	Create a track, pillar, stair, or tunnel template.
/dt editor tracks reset <kind> [all|unparent|promote]	Remove the template you're standing in. Same mode rule as contents reset when it heads a group.
/dt editor <tracks|portals> reset <kind> <name> [mode]	The same, addressed by name — what the editor screen's Remove sends. default is resettable: its files go (bundled copies too in dev mode) and the kind falls back to its built-in geometry.
/dt editor <tracks|portals> label <kind> <name> <label…>	Display label for a track-side template (works on bundled rooms, which rename refuses).
/dt editor portals group move <child> <new_parent>	Re-parent a dimensional-carriage sub-variant, keeping its weight, gate and Stage links.
/dt editor portals fog <next|auto|on|off>	Whether the room you stand in hides its boundary behind fog. Auto follows the walls mode.
/dt editor portals room <name> <setting…>	Every room setting — length/width/height/size, mode, lock, copies, doorwall, contents, sky, fog, exits, exitevery, exitmove, books… — addressed by name instead of by the plot under you. What the editor screen sends for a room you are only looking at.

Command	What it does
/dt editor part new <kind> <name> [source]	Create a new part template (floor / walls / roof / doors).
/dt editor part save	Save the current part plot.
/dt editor part reset <kind> <name>	Remove a part template.
/dt editor part set <variant> <kind> <name>	Replace a carriage's part list for a kind with one entry.
/dt editor part add <variant> <kind> <name>	Append a part to a carriage's list for a kind.
/dt editor part remove <variant> <kind> <name>	Remove a part from a carriage's list.
/dt editor partmenu on|off	Toggle the auto-opening Part Variant Menu inside carriage plots.

The reserved part name none means "stamp nothing for this kind."

Command	What it does
/dt editor weight <variant> <0-100>	Set a carriage template's spawn weight.
/dt editor tracks weight <kind> <name> <0-100>	Set a track-side template's weight.
/dt editor contents weight <id> <0-100>	Set a contents template's weight.
/dt editor layout rooms|halves|group <n|inc|dec>	Set how often a group is filled with three Rooms, two Halves or one Group carriage. Bare layout prints all three.
/dt editor shell-size <variant> room|half|full	Resize a carriage template and move it to that size's row.
/dt editor pool-move <carriage|whole|contents> <id> <to> [name]	Move a template to another pool at its own size (never reshaped); the original is removed. (v0.1291.0)
/dt editor workbench {list|goto|save|test|remove|commit [replace] <id> <kind> [<sub|-> [<name> [<parent>]]]}	The Workbench staging category: list, visit, save, test (as its relay kind, without committing — v0.1294.0), drop or commit a staged relay build. (v0.1291.0)
/dt editor whole half new <name> [source]	A new whole half (corridor-length whole carriage); editor-only for now. (v0.1291.0)
/dt editor shell-wins <variant> on|off	Whether the carriage keeps its own blocks where its contents overlap them.
/dt editor half-join wall|bridge|short|random	How a pair of Half carriages closes the gap between them.

Weight 0 retires a template without deleting it. Default is 1.

Beyond weight, each weighted template can be limited to where it spawns — a difficulty-level range and a set of worldgen phases.

Command	What it does
/dt editor minlevel <variant> inc|dec|<0-1000>	Lowest Diff-Level a carriage may spawn at.
/dt editor maxlevel <variant> inc|dec|<-1-1000>	Highest Diff-Level; -1 (dec past 0) = no cap ("all").
/dt editor phase <variant> <overworld|nether|void|end> on|off|others	Toggle a worldgen phase the carriage may spawn in. others flips every phase except the named one.
/dt editor contents minlevel|maxlevel|phase <id> …	The same three, for a contents template.
/dt editor tracks minlevel|maxlevel|phase <kind> <name> …	The same three, for a track / pillar / tunnel template.

Defaults — min 0, max all, all four phases — mean "spawns everywhere", so an untouched template behaves exactly as before. The X menu has matching Min Lv / Max Lv steppers and a Phases selector; the floating world-space panels show the same per row (four O N V E phase letters you click to toggle). See Templates ▸ Spawn gating.

These edit a template's own gate. If the template is linked to a Stage the Stage's gate wins and the write is inert until you detach — the command says so rather than reporting a bare success.

A Stage is a named, reusable spawn gate that many templates link to. Editing the Stage retunes every linked template at once.

Command	What it does
/dt editor stage list	List every Stage with its gate.
/dt editor stage new <id>	Create a Stage (lowercase a-z0-9_, 1–32 chars) with the default wide-open gate.
/dt editor stage rename <id> <name…>	Change a Stage's display name. Its id, and every link, stay put.
/dt editor stage builder <id> <uuid|none> [name…]	Credit the Stage to a builder (as a template's builder), or none to clear. The X menu's Built by picker sends this.
/dt editor stage delete <id>	Delete a Stage. Templates linked to it fall back to their own inline gate.
/dt editor stage minlevel|maxlevel|phase <id> …	Edit the Stage's gate — same arguments as the per-template versions above.

Command	What it does
/dt editor stage apply carriage <id> <stage|custom>	Link a carriage to a Stage, or custom to detach.
/dt editor stage apply contents <id> <stage|custom>	Same, for a contents template.
/dt editor stage apply tracks <kind> <name> <stage|custom>	Same, for a track / pillar / tunnel template.
/dt editor stage apply contents-group <parent> <child> <stage|custom>	Same, for a sub-variant member (these may hold several links).

Detaching snapshots the Stage's current gate into the template's inline gate, so nothing moves the moment you unlink.

Command	What it does
/dt editor stage select <id>	Focus a Stage — preview every carriage for it and default new parts to it. Repeat to toggle off.
/dt editor stage deselect	Clear the focused Stage.
/dt editor stage filterparts	Hide part plots the focused Stage doesn't use.
/dt editor stage duplicate <id> [newid]	Fork a Stage with its parts and their assignments.
/dt editor stage blocks <id>	List the Stage's parts and the unique blocks in them.
/dt editor stage replaceblock <id> <from> <to>	Swap a block across every part in the Stage — NBT and variant sidecars.

Command	What it does
/dt editor variant list	Print every position with a variant pool in the current plot.
/dt editor variant clear	Remove the variant entry at the block you're looking at.
/dt editor variant overlay on|off	Toggle the white sparkle outline on marked blocks.

Command	What it does
/dt editor blocks	Open the template-blocks menu for the plot you're standing in — lists every block used (with counts), previews on click, and swaps everywhere (with orientation preserved) via the Swap button. Same as pressing V.

See Feature: Template Blocks Menu for the full write-up.

Command	What it does
/dt debug reroll <prefabId>	Re-roll every loaded container BE whose state matches <prefabId>'s source block. One-shot fix for already-spawned carriages whose contents were rolled before a template edit landed.
/dt debug loot-rolls on|off	Toggle per-furnace-roll diagnostics — K, fill bounds, pinned-slot counts, what each slot picked. Off by default. Also surfaced as a Toggle in the in-world Debug menu.

Command	What it does
/dt package list	List every installed package and its state.
/dt package save <name>	Save the active package's folder as dtpacks/<name>.zip.
/dt package activate <name>	Make <name> the active package — new edits land there.
/dt package enable <name>	Enable a package's content in the spawn pool.
/dt package disable <name>	Disable a package's content without deleting it.
/dt editor import	Re-scan dtpacks/ for new zips and folders.
