A hotkey or shortcut is a key or set of keys that performs a predefined function. These functions can often be done via some other, more indirect mechanism, such as using a menu, typing a longer command, and/or using a pointing device.
The Dominions game series has a large number of hotkeys available, depending on the context that the game screen is in at the moment, if it's on the strategic overview map or the battlescreen display for example.
These hotkeys can be used when the strategic map is active, where you can see the provinces on the map and move your armies around. A list with most, but not all of them, is displayed when using the "?" hotkey.
