# Pull Request Template ## Description This PR will fix an error `TypeError cannot read properties of undefined (reading '$el')` with the keyboard shortcut `Alt+KeyA` for triggering the file picker. **Issue** I couldn't able reproduce this issue. It might be because `$children` was unavailable at the time of access. **Solution** Previously, it relied on `$children`. Now, it uses the more reliable `querySelector` method to find the target element.
