I would like to suggest a key to repeat the last action. For example, if I'm in an idle state after throwing an item like a javelin, and I still have javelins remaining in my inventory, the character should automatically equip and aim another javelin without having to go through the steps again (T > scroll down to the javelin > aim > shot). This could be triggered by a key like TAB, to repeat the last action when in an idle state.
