+# Example Workflow: Using Trigger Words with LoRA Batch Testing
+
+This document provides a step-by-step guide to create a workflow that tests multiple LoRAs with their respective trigger words.
+
+## Scenario
+
+You want to test 3 different style LoRAs on the same prompt to see which produces the best results. Each LoRA requires a specific trigger word.
+
+## LoRAs to Test
+
+1. `anime_style_v1.safetensors` → Trigger word: "anime style, masterpiece"
+2. `photorealistic_v2.safetensors` → Trigger word: "photorealistic, 8k uhd"
+3. `oil_painting.safetensors` → Trigger word: "oil painting, classical art"
+
+## Step-by-Step Setup
+
+### 1. Add Efficient Loader Node
+
+**Settings:**
+- `ckpt_name`: Your base model (e.g., "sd_v15.safetensors")
+- `positive`: "a beautiful mountain landscape at sunset"
+- `negative`: "low quality, blurry"
+- Leave `lora_name` as "None" (we'll use the XY Plot instead)
+
+### 2. Add XY Input: LoRA Plot Node
+
+**Settings:**
+- `input_mode`: "X: LoRA Batch, Y: LoRA Weight"
+- `X_batch_path`: Path to your LoRA folder (e.g., "D:\LoRAs" or "/home/user/loras")
+- `X_subdirectories`: false
+- `X_batch_sort`: "ascending"
+- `X_batch_count`: 3
+- `model_strength`: 1.0
+- `clip_strength`: 1.0
+
+**NEW - Trigger Words Field:**
+```
+X_trigger_words:
+anime style, masterpiece
+photorealistic, 8k uhd
+oil painting, classical art
+```
+
+**Important:** Make sure the trigger words are in the same order as your sorted LoRAs!
+
+### 3. Add XY Input: LoRA Plot Node (for Y-axis)
+
+For the Y-axis, we'll vary the LoRA weights:
+
+**Settings:**
+- This node provides the Y values for the weight variations
+- Connect the Y output from the LoRA Plot node configured in step 2
+
+OR use a separate simple value node if you prefer fixed weight steps.
+
+### 4. Add XY Plot Node
+
+**Settings:**
+- Connect the `X` output from the LoRA Plot node to the XY Plot's `X` input
+- Connect the `Y` output to the XY Plot's `Y` input
+- `grid_spacing`: 5
+- `XY_flip`: True (if you want LoRAs on X-axis)
+
+### 5. Add KSampler (Efficient) Node
+
+**Settings:**
+- Connect `script` input to the XY Plot node's output
+- Connect `model`, `positive`, `negative`, `latent` from the Efficient Loader
+- Set your sampling parameters (steps, CFG, sampler, etc.)
+
+### 6. Add Save Image Node
+
+Connect the output from KSampler to save your results.
+
+## Expected Results
+
+When you run this workflow, you'll get an XY plot grid with:
+
+**X-axis (LoRAs):**
+- Column 1: Images generated with anime_style_v1 LoRA
+  - Prompt used: "a beautiful mountain landscape at sunset anime style, masterpiece"
+- Column 2: Images generated with photorealistic_v2 LoRA
+  - Prompt used: "a beautiful mountain landscape at sunset photorealistic, 8k uhd"
+- Column 3: Images generated with oil_painting LoRA
+  - Prompt used: "a beautiful mountain landscape at sunset oil painting, classical art"
+
+**Y-axis (Weights):**
+- Varying LoRA strengths as configured
+
+## Tips
+
+1. **Verify LoRA Order:** Run the workflow with `X_batch_count: 1` first to verify which LoRA is loaded first, then adjust your trigger words accordingly.
+
+2. **Empty Trigger Words:** If a LoRA doesn't need a trigger word, just leave that line blank:
+   ```
+   anime style, masterpiece
+   
+   oil painting
+   ```
+   (The second LoRA has no trigger word)
+
+3. **Test Individually First:** Before running a large batch, test each LoRA individually with its trigger word to ensure you have the correct trigger words.
+
+4. **Combine with Other XY Inputs:** You can also combine LoRA batching with checkpoint variations, sampler variations, etc.
+
+## Troubleshooting
+
+**Problem:** Trigger words aren't being applied
+- **Solution:** Check that you've entered trigger words in the `X_trigger_words` field (multiline text area)
+
+**Problem:** Wrong trigger word applied to wrong LoRA
+- **Solution:** Verify your LoRAs are sorted in the expected order. Use the same sort order for trigger words.
+
+**Problem:** Too many/too few trigger words
+- **Solution:** The number of trigger words should match `X_batch_count`. Extra trigger words are ignored, missing ones default to empty.
+
+## Advanced: Combining with Prompt S/R
+
+You can use Prompt Search & Replace in combination with trigger words for even more control:
+
+1. Set up your LoRA Plot with trigger words as above
+2. Add an **XY Input: Prompt S/R** node for Y-axis instead
+3. This allows you to vary both the LoRA (with its trigger word) and parts of the prompt simultaneously
+
+Example:
+- X-axis: Different LoRAs (each with trigger word)
+- Y-axis: Replace "sunset" with ["sunrise", "midday", "midnight"]
+
+Result: Each LoRA tested across different times of day, with appropriate trigger words applied.
