Hi @GuilhermeHirsch
When you're not able to automate by capturing UI elements, best alternatives are navigating by keys (shortcuts) or images.
As @MichaelAnnis suggested, you can use hot keys / keyboard shortcuts in your app. I tested here and worked fine.
Be sure to use 'Focus windows' action prior to sending keys. I guess this is why it didn't work for you.
Use this:
1. Launch your app
2. 'Focus windows', by title = Nota Fiscal Gaúcha*
3. 'Send keys' {Alt}(A) (as an example)
