Quick question.  So I added in a split right shift, but I can't seem to figure out how to add it in with QMK.  
I tried to just add an extra declaration, (using KC_DEL as a holder here) but it says it's too many declarations:
KC_LSFT,         KC_Z,   KC_X,   KC_C,   KC_V,   KC_B,   KC_N,   KC_M,   KC_COMM,KC_DOT, KC_SLSH,    KC_RSFT,  KC_DEL,  \
says I gave it 63 instead of 62.  Ideas?  Thanks in advance.
