When you have created your invoice proposal, then instead of having to click "Post" and then OK two times for generating your invoice - Could you make a short cut, fx. Ctrl+B (or anything else), and then it would post and generate an invoice.

I know this can only be used if you don't need to make any alterations in printing and otherwise, but it would save 3 clicks. Or is there a way where you can make it so we have the option to make our own shortcuts?
