I tried multiple times, asked ai, but couldn't find, if we can open a file or script thru any action?

I tried much, thru chatgpt and perplexity and gemini, but couldn't make InputRempapper (or keyd) to open a file or script thru its actions. Can it be some how done? Can you give any example? I tried this action, but evne this sample action given by you gives 'grab error'.:> key_down(symbol: str) key_up(symbol: str)
