 You could use the builtin [`map`] function (or similar) to do something like this:
 
 ```nix
-keymaps =
-  (builtins.map (key: {
-    inherit key;
-    action = "<some-action>";
-    options.desc = "My cool keymapping";
-  }) ["<key-1>" "<key-2>" "<key-3>"])
-  ++ [
-    # Other keymaps...
-  ];
+{
+  keymaps =
+    (builtins.map (key: {
+      inherit key;
+      action = "<some-action>";
+      options.desc = "My cool keymapping";
+    }) ["<key-1>" "<key-2>" "<key-3>"])
+    ++ [
+      # Other keymaps...
+    ];
+}
 ```
 
 This maps a list of keys into a list of similar [`keymaps`]. It is equivalent to:
 
 ```nix
-keymaps = [
-  {
-    key = "<key-1>";
-    action = "<some-action>";
-    options.desc = "My cool keymapping";
-  }
-  {
-    key = "<key-2>";
-    action = "<some-action>";
-    options.desc = "My cool keymapping";
-  }
-  {
-    key = "<key-3>";
-    action = "<some-action>";
-    options.desc = "My cool keymapping";
-  }
-  # Other keymaps...
-];
+{
+  keymaps = [
+    {
+      key = "<key-1>";
+      action = "<some-action>";
+      options.desc = "My cool keymapping";
+    }
+    {
+      key = "<key-2>";
+      action = "<some-action>";
+      options.desc = "My cool keymapping";
+    }

+    }
+    # Other keymaps...
+  ];
+}
 ```
