+# Use a keyboard to use Azure Machine Learning designer (preview)
+
+Learn how to use a keyboard and screen reader to use Azure Machine Learning designer. For a list of keyboard shortcuts that work everywhere in the Azure portal, see [Keyboard shortcuts in the Azure portal](../azure-portal/azure-portal-keyboard-shortcuts.md)
+
+This workflow has been tested with [Narrator](https://support.microsoft.com/help/22798/windows-10-complete-guide-to-narrator) and [JAWS](https://www.freedomscientific.com/products/software/jaws/), but it should work with other standard screen readers.
+
+## Navigate the pipeline graph
+
+The pipeline graph is organized as a list of lists. The top-level module list contains all of the module in the pipeline. Each item in the module list contains a connection list that describes all of its connections. 
+
+1. In the module list, use the arrow key to switch modules.
+1. Use tab to open the connection list for the target module.
+1. Use arrow key to switch between the connection ports for the module.
+1. Use “G” to go to the target module.
+
+## Edit the pipeline graph
+
+### Add a module to the graph
+
+1. Use Ctrl+F6 to switch focus from the canvas to the module tree.
+1. Find the desired module in the module tree using standard treeview control.
+
+### Edit a module
+
+To connect a module to another module:
+
+1. Use Ctrl + Shift + H when targeting a module in the module list to open the connection helper.
+1. Edit the connection ports for the module.
+
+To adjust module properties:
+
+1. Use Ctrl + Shift + E when targeting a module to open the module properties.
+1. Edit the module properties.
+
