 The tool utilizes a two-tiered configuration system managed by the `configuration.py` module:
 
 1.  **Application Settings (`config/app_settings.json`):** This JSON file defines the core global default settings, constants, and rules that apply generally across different asset sources (e.g., the global `OUTPUT_DIRECTORY_PATTERN` and `OUTPUT_FILENAME_PATTERN`, standard image resolutions, map merge rules, output format rules, Blender paths, `FILE_TYPE_DEFINITIONS`, `ASSET_TYPE_DEFINITIONS`). See the [User Guide: Output Structure](../01_User_Guide/09_Output_Structure.md#available-tokens) for a list of available tokens for these patterns.
+*   **`FILE_TYPE_DEFINITIONS` Enhancements:**
+        *   **`keybind` Property:** Each file type object within `FILE_TYPE_DEFINITIONS` can now optionally include a `keybind` property. This property accepts a single character string (e.g., `"C"`, `"R"`) representing the keyboard key. In the GUI, this key (typically combined with `Ctrl`, or standalone like `F2` for asset naming) is used as a shortcut to set or toggle the corresponding file type for selected items in the Preview Table.
+            *Example:*
+            ```json
+            "MAP_COL": {
+                "description": "Color/Albedo Map",
+                "color": [200, 200, 200],
+                "examples": ["albedo", "col", "basecolor"],
+                "standard_type": "COL",
+                "bit_depth_rule": "respect",
+                "is_grayscale": false,
+                "keybind": "C"
+            },
+            ```
+        *   **New File Type `MAP_GLOSS`:** A new standard file type, `MAP_GLOSS`, has been added. It is typically configured as follows:
+            *Example:*
+            ```json
+            "MAP_GLOSS": {
+                "description": "Glossiness Map",
+                "color": [180, 180, 220],
+                "examples": ["gloss", "gls"],
+                "standard_type": "GLOSS",
+                "bit_depth_rule": "respect",
+                "is_grayscale": true,
+                "keybind": "R"
+            }
+            ```
+            Note: The `keybind` "R" for `MAP_GLOSS` is often shared with `MAP_ROUGH` to allow toggling between them.
 2.  **LLM Settings (`config/llm_settings.json`):** This JSON file contains settings specifically related to the LLM predictor, such as the API endpoint, model name, prompt template, and examples. These settings can be edited through the GUI using the `LLMEditorWidget`.
 3.  **Preset Files (`Presets/*.json`):** These JSON files define supplier-specific rules and overrides. They contain patterns to interpret filenames, classify map types, handle variants, define naming conventions, and specify other source-specific behaviors.
