Certainly Talidan I will give a complete description of my key configuration and how I use them.
In SA-MP if I press Up/Down at the same time it will turn my character around 180 degrees then I can let go of the up key while still holding down and continue running in that direction which allows me to shoot at targets that are facing my back. The problem is in MTA when I try and do this the character just stops dead still which really messes up the way I play this game.
This is how I position my hand for controlling this way note the index fingers handles all directional key movements and is position so I can press up/down at the same time.
