Is it necessary to remap a command?

No. The game profile contains all commands in the game. Each command is assigned to the button, axis, or POV best suited for effective game play.

For most games, the preconfigured commands in the game profile should meet your needs. However, you can add a custom command to your game at any time.

Is it necessary to map a command to each direction of the axis or POV?

To answer this question, it is important that you understand how axis and POV commands work. Because an axis has two directions (X axis and Y axis), it requires a command for each direction. Like an axis, a POV has multiple directions, and therefore requires a command for each direction. POVs have four or eight direction commands. Axis and POV commands are called combination commands.

If you edit the command mapping for one direction of an axis or POV command, you should edit the command mapping for the other direction(s) as well. If you do not, WingMan Profiler will use the default command(s) mapped to the other direction(s). This may or may not prove advantageous in combination with the command you mapped to the first direction.

What is the difference between editing an existing command's mapping and mapping a new command?

Editing an existing axis or POV command's mapping and mapping a new axis or POV command are essentially the same. The only differences are that
