Right, except it wasn't done well in this case. The game is great, the UI not so much. Some menus require the arrow keys to navigate, some +-, others hjkl.

It's been a while since I last played, but there is a "Designation" menu which orders your dwarves to perform specific tasks. You want them to build a staircase where there was some rock before? Awesome, they'll do it. You want them to build a staircase after you already mined the block? No can do. No warning, no error message, simply nothing happens. You need to go through the other menus, build a staircase and move it there.
