Welp scratch all of that. Either I was mistaken or it got "patched" out because it does not work....f*ck if I know You can also ad this line to mapping: <button id="IK_Shift" val="1.0" overridableUI="forward"/> // Yes, you are mapping ' overridableUI="forward" ' twice It will allow you to sprint forward (if you are not pressing W at the same time). Ultimately I found it equally awkward but maybe it does it for you.
