I tested ti for different buttons / commands, but it is really inconvenient. The way is too long to be useful. It is much easier to click on the button.
What I am asking for is to be able to add keyboard custom shortcuts to the most frequently used commands – Add (default – e.g. Alt+A) and Duplicate (Quick – e.g. Alt+D+1 and Custom – e.g. Alt+D+2) and Edit item – e.g. Alt+E, Batch Edit – Alt+B.
I don’t know how complicate it is to be implemented, but in any case it should be very useful.
