Hi and welcome to the Bome community!
First of all, it is important that the application in question has current focus (is active) before sending keystrokes. See this tutorial. Also note that by default if MIDI translator is focused, no keystrokes are sent. This is primarily as an aide so that keystrokes aren’t sent to Bome MIDI Translator Pro while programming it and can be changed in the settings.
For complex keystroke sequences, please refer to this posting. In summary, complex key sequences need to be programmed through a series of translators.
