 #' @param data A data frame, or an object that can be coerced to a data frame.
-#' @param pattern Character vector. For `data_rename()`, indicates columns that
-#'   should be selected for renaming. Can be `NULL` (in which case all columns
-#'   are selected). For `data_addprefix()` or `data_addsuffix()`, a character
-#'   string, which will be added as prefix or suffix to the column names. For

-#'   are used as values for the `replacement` argument (i.e. `pattern` can be a
-#'   character vector using `<new name> = "<old name>"` and argument `replacement`
-#'   will be ignored then).
-#' @param replacement Character vector. Indicates the new name of the columns
-#'   selected in `pattern`. Can be `NULL` (in which case column are numbered
-#'   in sequential order). If not `NULL`, `pattern` and `replacement` must be
-#'   of the same length. If `pattern` is a named vector, `replacement` is ignored.
+#' @param pattern Character vector.
+#'   - For `data_addprefix()` or `data_addsuffix()`, a character string, which
+#'     will be added as prefix or suffix to the column names.
+#'   - For `data_rename()`, indicates columns that should be selected for

+#' @param replacement Character vector. Can be one of the following:
+#'   - A character vector that indicates the new names of the columns selected
+#'     in `pattern`. `pattern` and `replacement` must be of the same length.
+#'   - `NULL`, in which case columns are numbered in sequential order.
+#'   - A string (i.e. character vector of length 1) with a "glue" styled pattern.
+#'     Currently supported tokens are:
+#'     - `{col}` which will be replaced by the column name, i.e. the
+#'       corresponding value in `pattern`.
+#'     - `{n}` will be replaced by the number of the variable that is replaced.
+#'     - `{letter}` will be replaced by alphabetical letters in sequential order.
+#'       If more than 26 letters are required, letters are repeated, but have
+#'       sequential numeric indices (e.g., `a1` to `z1`, followed by `a2` to `z2`).
+#'     - Finally, the name of a user-defined object that is available in the
+#'       environment can be used. Note that the object's name is not allowed to
+#'       be one of the pre-defined tokens, `"col"`, `"n"` and `"letter"`.
+#'
+#'     An example for the use of tokens is...
+#'     ```r
+#'     data_rename(
+#'       mtcars,
+#'       pattern = c("am", "vs"),
+#'       replacement = "new_name_from_{col}"
+#'     )
+#'     ```
+#'     ... which would return new column names `new_name_from_am` and
+#'     `new_name_from_vs`. See 'Examples'.
+#'
+#' If `pattern` is a named vector, `replacement` is ignored.
 #' @param rows Vector of row names.
 #' @param safe Do not throw error if for instance the variable to be
 #'   renamed/removed doesn't exist.
