This workflow shows how to build a simple workflow to get directions home. The workflow starts with an address (in this case the Apple store in Leeds, UK). The user is then given a list of transportation types to choose from.
Once selected, a Show Directions action is triggered for the Google Maps service with the transportation type selected.
The workflow could be simplified to simply offer the Ask When Run option on the Show Directions. However I prefer to have a nice menu option with the question on it. But there is another consideration. If you wanted to use this as a notification centre widget entry, using the menu option will display the list in situ in the notification centre whereas the Ask When Run approach will bounce the user into Workflow which makes the overall process a little less streamlined.
