By now you should now have your most of your items equipped on your body, with only your treatment kit and first aid kit left in your inventory. Your nano programs should also be stored in the Program window. You may use the items in your inventory and nano programs by clicking on the icons in their windows. However, to help speed things up and make managing your character easier, you have been given an Action Bar.

The Action Bar is the thin transparent bar near the top of your screen. You can hide/show it by pressing ‘y’ on your keyboard. If you left-click your treatment kit, drag it so it's over the Action Bar, and then left-click again the treatment kit will be placed in the Action Bar. Do this for your first aid kit and your nano program(s) as well.

The Action Bar allows you to quickly access an item without the need to open the windows which may end up cluttering your screen. To use an item in the action bar, simply press a number from 1 to 0 that corresponds with the placement of the item in the Action Bar. The first box in the Action Bar is 1, the second is 2 and so on so the last box is 0. We will cover how to use the items you have later.
