Definately not normal, unless you like whacking critters with your staff
You should see a bar of 10 empty boxes somewhere on your screen (if not press P) ; that is your hotkey bar (associated with the numbers along the top of the keyboard). Clicking the '+' on the bar opens up a second hotkey bar and the curved arrow allows you to orient the bars vertically/horizontally. The '-' button will close the second bar (the second bar is associated with the numeric keypad). They can be dragged to whatever screen location you like (click+drag on the number)
I believe you can customize 6 bars but only have 2 visible at a given time ; the up/down arrows on the side of the bars allow you to select which bars you want to use.
After leveling up press 'K' and that will open up your Skills List ; each tab shows the skills you can learn at your level and their associated cost (you gain skill points every level). More skills will become available as you level up. Once you have decided which skill you wish to learn, press the up arrow next to it. You can then drag those skill icons to the hotkey bar ; then to use them just choose the target and hit the hotkey. Some don't need a target (many buffs), others do require a target. To target yourself you can press F1 when not in a party.
To see what skill does, hover the pointer over the icon ; once you have the 1st level of a skill you can hover over the text on the Skill List next to it to see the description of the next level (if there is one)
Other actions are available from the Sub-Menu (press 'B') ; Attack and Pick-Up are two I use from that menu ; simply drag those icons to a hotkey. Other items can also be hotkeyed ; alternate weapons, potions, scrolls.
Hope this helps.
