Vampire the Masquerade: Redemption does not feature customizable keyboard/mouse controls. All shortcuts for the game's basic and advanced functions are pre-determined and seem to be hardcoded. Fortunately, the game engine recognizes when keys are remapped in the system registry via utilities such as KeyTweak, facilitating the adjustment of particularly hard-to-use defaults as a last resort.
A greater challenge, however, lies in finding out which keys are assigned to what functions in the first place, as in Redemption's case such information is exceedingly poorly documented and very hard to obtain in its entirety - a significant portion of controls is listed in the official Manual, which is not readily available in digital form as part of the original retail release. A scanned copy of this document may be obtained via the provided link, with newer (digitally redistributed) copies of the game, or found on P2P file sharing networks such as eMule. Even so, the manual does not mention many other useful hotkeys which do exist in the game and could make your playthrough much more fluid and enjoyable. The only way to find out about such unmentioned controls is through serendipity, trial and error. Therefore, the tables below aim to provide the most extensive list of keyboard and mouse shortcuts found in the game so far.
