[PerformanceCodelab](Step 4 Analyze performance with system tracing) perfetto keyboard keys description problem

hi, when I was following the codelab [PerformanceCodelab](https://developer.android.com/codelabs/jetpack-compose-performance?continue=https%3A%2F%2Fdeveloper.android.com%2Fcourses%2Fpathways%2Fjetpack-compose-for-android-developers-4%23codelab-https%3A%2F%2Fdeveloper.android.com%2Fcodelabs%2Fjetpack-compose-performance#3) and tried to use perfetto to practise reading the trace file, I found that some of the keyboards keys not worked as mentioned.

1. [wrong] W and A keys for zoom in/out, [right] W and **S** keys for zoom in/out
2.[wrong] S and D for going left and right, [right] **A** and D for going left and right

maybe the perfetto website update the hotkeys ,and hope codelab to be updated

Open the linked PerformanceCodelab and review Step 4, “Analyze performance with system tracing,” alongside the current Perfetto keyboard behavior. Update the key descriptions so W/S are documented for zooming and A/D for moving left and right, then verify the codelab wording matches the current controls.
