Show specific PowerPoint slide from Excel (based on header text)

Dear Excel/VBA specialists,

I have a short question...

I am looking for (a simple as possible) VBA code that does the following (pseudo code).

1. A user clicks on a button in Excel (that's easy to create
2. The button opens a specific PowerPoint file. For example: C:\Temp\dod.pptx
3. Search for a specific text in the PowerPoint Presentation (for example: -TEST-).
4. Show that specific slide as full screen.
5. When ESC is pressed, close the PowerPoint file and go back to the Excel file

Is this easy to create?

Thank you (very much) in advance for you answer.

Best regards,

Hans
