1) to drop stuff from inventory, hold shift, then click on it. If you have 2 or less items, they select individually. If you have 3+ items, an option comes up to select how many you want.
2) Hit tab, as in inventory. At the bottom right, next to magic is a compass. Click on that. the row of icons above it are: 1) local map. 2) world map and fast travel. click on a location. 3) active quest 4) journal/quests
3) Similiar to 2, click the health/magicka/fatigue bars, you can see all your stats here by clicking the different icons.
