I have a laptop without a numeric keypad on which I'm running Ubuntu 12.04, and I very much enjoy playing roguelike games. Such games tend to require a numpad for movement, targeting, &c., as one is able to operate in the eight cardinal directions. To get around the limitation of not having a numpad, I would like to be able to bind a key combination, for example Shift + Left Arrow to another key, in this case 1; unfortunately, my research so far has only turned up how to bind a key combination to a command. I'm sure there's something blaringly obvious that I'm missing, but as for what it is ...
Any help would be greatly appreciated!
