How do I set hotkeys?
Go to the tab Hotkeys under Options in General Controls. To assign a hotkey, click in the field beside an action of your choice. If there is already a hotkey assigned to this action, the selected key (combination) will turn bold. If no key has been selected yet, the text will appear. By clicking a second time in this field, the key or the text will turn to italics. Now, press the key or the key combination to which you want to assign the action. Click on "Okay" at the end of the page to save the changes.
