This is a 3.6.2 Patch 11. Editor:

• Room Editor supports Del key for deleting objects.
• Fix clicking on a room background when in the "Character" or "Object" mode does not select the Room in the property grid. Engine:
• Game.SimulateKeyPress() now supports composite key codes, such as eKeyCtrlA and eKeyAlt, and simulates two key presses in this case (regular and mod key).
• Fixed key + mod combinations are not passed into the "on_key_press" callback properly when in the "new" key handling mode (regression since the last patch).
• Fixed couple of mistakes in a smooth walk transition, introduced by the previous patch.
