So I noticed from another thread that the building rotation hasn't been adapted to the PC version yet.   From a user perspective these are the options I tried before I realised that it hadn't been put in yet;

After selecting the building type to rotate placement I tried;

* Q & E keys

* Ctrl Q & E

* Alt Q & E

* Shift Q & E

* Arrow keys (with Ctrl, Alt & Shift press variants)

* Keypad 4 & 6 (with Ctrl, Alt & Shift press variants)

For map rotation with the mouse I tried;

* Ctrl - left click and mousemove

* Alt - left click and mousemove

* Shift - left click and mousemove

* Right mouse down (with Ctrl, Alt & Shift press variants)

So lots of options there for both ideas.

If I was to list my preference to both I'd personally say;

After selecting the building type to rotate placement - Q & E keys

Map rotation with the mouse - Right mouse down, sweeping left or right for movment.

Any other thoughts ?
