Tool textures are special textures which control how the map is compiled. These are the tool textures used by Vluzacn's ZHLT v34. They are found in halflife.wad and zhlt.wad. For detailed usage of each texture, refer to it's individual wiki page.

Image	Name	Allowed as world	Allowed as entity	Casts shadows as world brush	Has lightmap	Cuts visleaves	Solid to cliphull 1	Solid to cliphull 2	Solid to cliphull 3	Solid to bullets	Info
N/A	!cur_0*	Yes	No	Yes	No	Yes	No	No	No	No	Acts like `CONTENTWATER` and `func_pushable` with a speed of 2048 units/s in +X. This texture is always fullbright.
N/A	!cur_180*	Yes	No	Yes	No	Yes	No	No	No	No	Acts like `CONTENTWATER` and `func_pushable` with a speed of 2048 units/s in -X. This texture is always fullbright.
N/A	!cur_270*	Yes	No	Yes	No	Yes	No	No	No	No	Acts like `CONTENTWATER` and `func_pushable` with a speed of 2048 units/s in -Y. This texture is always fullbright.
N/A	!cur_90*	Yes	No	Yes	No	Yes	No	No	No	No	Acts like `CONTENTWATER` and `func_pushable` with a speed of 2048 units/s in +Y. This texture is always fullbright.
N/A	!cur_dwn*	Yes	No	Yes	No	Yes	No	No	No	No	Acts like `CONTENTWATER` and `func_pushable` with a speed of 2048 units/s in -Z. This texture is always fullbright.
N/A	!cur_up*	Yes	No	Yes	No	Yes	No	No	No	No	Acts like `CONTENTWATER` and `func_pushable` with a speed of 2048 units/s in +Z. This texture is always fullbright.
	`AAATRIGGER`	Yes	Yes	Yes	No	Yes	Yes	Yes	Yes	Yes	Identical to `NULL`, but shouldn't be used on world brushes as it may cause bugs. Useful for differentiating entities in the editor.
	`BEVEL`	Yes	Yes	Yes	No	No	No	Yes	No	Yes	Acts like `NULL`, however it changes the clipnode of a brush in a way that any player approaching the brush will not be collide with the brush until their origin reaches the plane that the `BEVEL` face lies on. It can be used to eliminate exterior corner clipping bugs, and any remaining clipping bugs that the `-cliptype precise` CSG parameter may miss.
	`black_HIDDEN`	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Identical to `NULL`, but has a lightmap. Brushes with this texture can cast shadows. This texture will not render as black except in Sven Co-op.
	`BOUNDINGBOX`	No	Yes	No	No	No	No	No	No	No	Acts like `ORIGIN`, but can be used to define a bounding box for an entity. Useful if you have a lot of complex, off-grid geometry and need a bounding box which is snapped to the grid.
	`CLIP`	Yes	Yes	No	No	No	Yes	Yes	Yes	No	Creates clipnodes on all three cliphulls.
	`CLIPBEVEL`	Yes	Yes	No	No	No	No	No	Yes	No	Acts like `BEVEL` but for clipnodes.
	`CLIPBEVELBRUSH`	Yes	Yes	No	No	No	No	No	Yes	No	Acts like `CLIPBEVEL`, but affects every single face.
	`CLIPHULL1`	Yes	Yes	No	No	No	Yes	No	No	No	Creates clipnodes on hull 1, used by standing players.
	`CLIPHULL2`	Yes	Yes	No	No	No	No	Yes	No	No	Creates clipnodes on hull 2, used by large monsters (apache, gargantua, gonarch, etc).
	`CLIPHULL3`	Yes	Yes	No	No	No	No	No	Yes	No	Creates clipnodes on hull 3, used by crouching players.
	`CONTENTEMPTY`	Yes	Yes	No	No	No	No	No	No	No	Removes collision from a brush and marks it as an empty volume.
	`CONTENTWATER`	Yes	Yes	Yes	No	Yes	No	No	No	Yes	Marks the brush as a water volume that will not render anything outside of it. It also removes collision from a brush and mirrors the faces inside out.
	`HINT`	Yes	Yes	No	No	Yes	No	No	No	No	Faces with this texture will split visleafs, allowing you to optimize what parts of the map are visible. Other faces of the brush should be textured with `SKIP`.
	`NOCLIP`	Yes	Yes	Yes	No	Yes	No	No	No	Yes	Acts like `NULL`, but no cliphulls are generated. Similar to the `zhlt_noclip` keyvalue in entities.
	`NULL`	Yes	Yes	Yes	No	Yes	Yes	Yes	Yes	Yes	Removes the face of a brush it's applied to, however clipnodes are still generated.
	`ORIGIN`	No	Yes	No	No	No	No	No	No	No	Brushes with this texture will act as the point of origin for entities.
	`SKIP`	Yes	Yes	No	No	No	No	No	No	No	Ignores the face of a brush it's applied to. Should not be used on world geometry except with `HINT`, as it may cause bugs.
	`SKY`	Yes	No	No	No	Yes	Yes	Yes	Yes	Yes	Renders the skybox on faces with this texture, and emits light if all faces of a brush are textured with `SKY` and you have a `light_environment` or `light_spot` entity.
	`SOLIDHINT`	Yes	Yes	Yes	No	Yes	Yes	Yes	Yes	Yes	Used to eliminate unnecessary face subdivision, especially on complex shapes such as triangular terrain.
N/A	`SPLITFACE`*	Yes	Yes	No	No	No	No	No	No	No	Brushes with this texture will subdivide faces they touch. It can be used to eliminate bad lighting caused by opaque entities.
	`translucent`	Yes	No	Yes	Yes	Yes	No	No	No	No	Removes clipnodes and mirrors the brush faces inside out.

*This texture functions normally, but is missing from zhlt.wad

I made a version with legends and emojis. The aim is threefold:

trim the wasted space the table headers are using, and give more space for the description column
Immediately infer the properties with emojis without constantly having to look up the yes/no columns back to the header way up the page
hopefully get this to display better on mobile

For now it's in this comment for my personal use. If feedback is favourable then we can merge this version into the main page.

for the !cur textures, you can make them invisible by using the _HIDDEN suffix, so !cur_0 becomes !cur_0_HIDDEN

_HIDDEN suffixes doesn't work in entities for some reason. since models don't take lighting from brush entities anyway there's no use case for it, so probably just use NULL instead.
Found a way to use tool textures in a way which imparts its properties, but without having it be part of any resulting face of the brush, but it only works on MAP files. You just insert an additional line defining a plane of the brush using the tool texture of interest, but the plane is way, way out towards the extremities of the map that it never intersects with any other planes of the brush:

{
( 80 144 96 ) ( 80 144 32 ) ( 80 208 96 ) NULL [ 0 -1 0 0 ] [ 0 0 -1 16 ] 0 1 1
( 144 144 96 ) ( 144 144 32 ) ( 80 144 96 ) NULL [ 1 0 0 0 ] [ 0 0 -1 16 ] 0 1 1
( 80 208 32 ) ( 80 144 32 ) ( 144 208 32 ) NULL [ -1 0 0 -0 ] [ 0 -1 0 0 ] 0 1 1
( 144 144 96 ) ( 80 144 96 ) ( 80 208 96 ) NULL [ 1 0 -0 0 ] [ 0 -1 0 0 ] 0 1 1
( 144 144 96 ) ( 144 208 32 ) ( 144 144 32 ) NULL [ 0 1 0 -0 ] [ 0 0 -1 16 ] 0 1 1
( 144 208 32 ) ( 144 144 96 ) ( 80 208 96 ) NULL [ 1 0 -0 0 ] [ 0 -1 0 0 ] 0 1 1
( 80 208 96 ) ( 80 208 32 ) ( 144 208 32 ) NULL [ -1 0 0 -0 ] [ 0 0 -1 16 ] 0 1 1
( 32767 32768 32768 ) ( 32768 32768 32767 ) ( 32768 32767 32768 ) !CUR_0 [ -0.707107 0.707107 0 0 ] [ 0.408248 0.408248 -0.816497 0 ] 0 1 1
}

The above spawns a NULL brush but with cur_0 contents. I figure a map pre-processor like MESS could implement this featur, inserting tool texture faces into the resulting brush defs in the output .map.
