Of course! Use the enter key, you will see a menu (you can also click on the backpack icon, in the left up of your screen). By default, you'll see your items. Click on the arrows on the screen (not the ones on your keyboard, you'd just switch from one item to another), and you'll be able to see your quests (those available and those finished: click on a quest in progress so that it is set as the current one, and a yellow arrow will appear on the edge of your screen to show you the direction to take if it's known), the different maps of the game (the same ones that appear when you click to take the bus) and your relationships with the different characters as well as your own stats.
