How to select a field by its name within another application?

My objective here is to copy a word from Dictionary and paste it in the respective field in Anki, another application, whose window can shift around from time to time. Hence, I need to dispense with the old trick of having BTT move a mouse cursor over to a fixed area and left-click it to bring the field in question to focus.

I wonder if there's another way to select a field by its name, in this case "Word". I'm familiar with solutions like this in Java Script, but because i'm no longer in the domain of web browser, I'm at my wit's end.

Could anyone please guide me in the right direction?
