Hello everybody.

In an earlier feedback I was suggesting that the „E“ menu should be completely usable via keyboard commands. So I was thinking about this issue for a while now and have brought up some ideas:

Basically either the left or the right hand side of the menu is selected and has the focus. This can be highlighted with a border or simply a more intense colour. With the usage of the „WASD“ keys it shall be possible to move the cursor (selected item) to select the desired item. Using the „Shift“ key the item can then be pushed to the other side of the menu. A slight change is necessary then to the mouse usage of moving all items, which can be solved by pressing the „ALT“ key instead. So a single press on the „Shift“ key will move one item. Same goes with a single click. Either pressing „ALT + Shift“ or „ALT + left mouse key“ moves all selected items at once.
If it is not possible because the other container is full or any other reason, e.g. the container can not hold the desired item, there may be implemented a single red flash of the items background colour or something like that. This can also be applied to the normal mouse click gesture, because right now the menu systems lacks of any indication system.
To even further improve the clarity which items can be hold by the container (for example the furnace, which can not hold all possible items) it could be a solution to put some very transparent icons of the storable items to the menu, so that it is immediately visible to the player which items he can store in that very container. Inserting the matching objects then makes the transparent icon fully visible and shows the item count next to it.
Also for a limited container like a lorry there should be an item counter to show how many more ojects can be placed inside.

Back to the keyboard shortcuts. Only one side of the menu can be selected. If the very right end of the item list is approached the cursor shall move back to the first item or to the next row if there is any. Moving vertically between inventories or production slots is possible using "W" or "S".  To switch the menu sites simply use the „Q“ button which is a bit similar to the usage outside of the inventory menu to switch between recent items in the clonks inventory.
Using the straight of the mouse or the keys „ALT + W“ or „ALT + S“ can be used to switch between all possible containers on the selected side of the menu. Additionally to avoid cycling through all containers the usage of "ALT + <Number of Containers>" can be used to quickly jump to the desired container.
The numbers „1“, „2“, … „5“ can be used to switch the currently selected item with the one in the clonks inventory matching the pressed number. This makes it possible to quickly rearrange the clonks inventory. Additionally using the „Shift“ key and pressing the number makes it possible to move the item out of the clonks inventory and leaving an empty slot. The item gets then placed in the selected building or another appropriate container. If the Clonk itself is selected the item shall simply get dropped to the ground.
Moving all objects to other side is done by "ALT + A" or "ALT + D".

To create objects in a building also press the shift key (increase the number of items in the queue +1). The finished item the goes straight into the buildings own inventory. To indicate the progress of the production a little progress bar can be integrated below the craftable item. Activating the endless production works with „ALT + Shift“ Key. Also the „ALT“ Key has to be used then to activate the endless mode while using the mouse. Reducing the queued productions can be done via the „Delete“ key (decreases the queue -1). Aborting all queued items of the selected craftable object is done via "ALT + Delete".

So the above mentioned ideas could be a possible way of implementing that feature. Hopefully I managed to think about all possible interaction possibilities so that this suggestion can be used as a thought out concept.
Best regards, Happy Striker
