+The `issue_comment` event occurs for comments on both issues and pull requests. To determine whether the `issue_comment` event was triggered from an issue or pull request, you can check the event payload for the `issue.pull_request` property and use it as a condition to skip a job.
+
+For example, you can choose to run the `pr_commented` job when comment events occur in a pull request, and the `issue_commented` job when comment events occur in an issue.
+
+```yaml
+on: issue_comment
+
+jobs:
+  pr_commented:
+    # This job only runs for pull request comments
+    name: PR comment
+    if: ${{ github.event.issue.pull_request }}
+    runs-on: ubuntu-latest
+    steps:
+      - run: |
+          echo "Comment on PR #${{ github.event.issue.number }}"
+
+  issue-commented:
+    # This job only runs for issue comments
+    name: Issue comment
+    if: ${{ !github.event.issue.pull_request }}
+    runs-on: ubuntu-latest
+    steps:
+      - run: |
+          echo "Comment on issue #${{ github.event.issue.number }}"
+```
