The tokens used in world_gen.txt are at the bottom of each parameter description. To get the parameters used to generate a world you are already playing, press ESC then choose export images exporting any image will also create the world generation parameter file, for more information see this post. (See below for more info.) The F1 key comes in handy when editing this file while the game is still running. This is particularly useful because people will often post their parameter sets on the forum or wiki in text form. The world_gen.txt file can also be edited with a text editor. You will need to save the world gen parameters to this file, before you hit Enter to generate the world. The F1 and F6 keys will load and save all of the parameter sets to this file. Parameter sets are stored in the data/init/world_gen.txt file in the main DF directory. Using t you can change the name of the parameter set, but note that this will not affect the name of the world that is generated. You can also copy an existing set to a new one, allowing you to base a new set on an existing one.

Hitting a will add a new set to the end of the list. You can select the current set that you want to work with using the up and down directional keys. The list of already-defined parameter sets is in the upper-right corner. 8.45 Minimum Number of Mid/Low/High Characteristic Squares.8.42 Allow Init Options to Show Tunnels.8.41.1 Minimum/Maximum Natural Cave Size.8.37 Do Orographic Precipitation and Rain Shadows.8.35 Minimum/Desired River Start Locations.8.31 Allow Divination, Experiments, and Necromancy types.8.29 Number of Evil Cloud / Evil Rain Types.8.28 Number of Disturbance Interaction Types.8.27 Number of Regional Interaction Types.8.10.2 Interaction between Mesh Size and Variance.8.7 Cull Unimportant Historical Figures.8.6.2 Year to Begin Checking Megabeast Percentage.8.6.1 Percentage of Megabeasts and Titans Dead for Stoppage.
