APTv3 Layout

This is an alternate keyboard layout initially based on the work done in MTGAP and CTGAP.

Angle Mod

On traditional row-stagger keyboards, the bottom row keys on the left side can be difficult to press with the same fingers used for the home/top row in the same columns. One workaround popularized for the Colemak layouts is known as an Angle Mod.

This mod rotates the first 5 letters in the bottom row left by 1 spot, and the leftmost letter is wrapped around to the 5th spot (QWERTY b spot). In conjunction with the letter shifts, the intention is that you will also change the fingers you use, so the SFB/column relationships are maintained.

This is what that looks like on APTv3:

w g d f b q l u o y
 r s t h k j n e a i ;
  c m p v x z , . ' /

In this case, c is pressed with Ring, m with Middle, and pvx are all with Index.
