Do people really use things like this with only keyboard?
I haven’t read trough all the text.
But by playing around with the examples, i have no idea how to drag&drop with my keyboard.
Is there some standard for what keys do what in situations like this?
I myself never use the keyboards for anything but to type in text, everything else is 100% mouse.
Mostly because i can never memorize any programs secret hidden handshakes,
Anyway, there seems to be no obvious way to figure it out, and i see no real visual indicators.
