',' and '.' could also be used to strafe with a single key press, but this seems like a bit of an afterthought and was not mentioned in the manual. In the case of doom specifically, the arrow keys were used for moving/turning, control was used for firing, alt was used as a strafe-modifier and space was used as the activate button. Weapon selection was on the number keys, which was easy to remember, but not so convenient to press. Other important controls were typically in locations intended to be convenient for the left hand, often on modifier keys (presumably to minimize the possibility of key rollover issues). The default control setup in many FPS games of that era (at least, Wolf3D, Doom, Duke3D, and Quake), revolved around using the right hand on the arrow keys for moving forwards/backwards and for turning. Executable and IWAD resource differences are.

Summarized below are the main differences of each known version of the games as changes were made. Additionally, a few early versions were preserved by testers, which eventually made their way to public archives. With mouse freelook enabled, this is quite possibly the most accessible and definitive way. From 1993 to 1995, various versions of Doom and Doom II were released by id Software to address glitches and input from players and fans. As expected, it amps up the violent gameplay of the original, while remaining faithful to the original DOOM 64 mythos.

In FPS games of that era, players were not expected to (and in the case of doom, could not) explicitly aim vertically, they just had to aim horizontally and the game would take care of the vertical component. However, modders ported the game to DOOM long ago as a total conversion megawad, and Brutal Doom 64 is one of the best versions around.
