I’m also a friend of keyboard shortcuts. It would be interesting to hear what shortcuts you would like to have, and what it is that is possible in Things 3.
Don’t forget to mail these wishes to the Omni Group support, as this is a user forum only occasionaly viewed by The Omni Group! My suggestion is to be as specific as possible. Everybody wants a better application with better shortcuts, but it’s probably better chances to get that with explicit wishes.
This is about the only aspect of the application I really want improved. I use my iPad with a hardware keyboard when working and at present most other apps I use have much better keyboard support. It would be the icing on the cake.
