+#### Grid mode tokens
+
+When you are using grid mode, you can change part of the prompt for each column or row by selecting the token parameter
+and entering a comma-delimited list of partial prompts, while including `__column__` or `__row__` in [the prompt
+parameter](#prompt-parameter).
+
+For example, using the base prompt `a cute __column__ __row__` with the tokens:
+
+- column token
+  - red, green, blue
+- row token
+  - cat, dog, bird
+
+Will produce the following prompts:

+- `a cute red dog`
+- `a cute green dog`
