Tab on import fields

[alnetloc]

I use MMEX on a Mac and regularly import both csv and ofx files. The speed things up, I like to keep my hands on the keyboard, ideally, tabbing from one field to the next. So, for example, the attached screen shot shows I have to provide input or decide Payee (use existing or create new?) - when popup window appears the focus should be on the current/top selection (Use Existing Payee); from there I could keyboard down cursor or tab to select "new payee"; tab again to select existing payee (by typing name); tab again to select category; etc. But, it appears (at least on my setup) that I can not tab or cursor from field to field. Is there a setting I'm missing? Or is this a feature request? This could greatly speed up my data imports. Much appreciated!
