So, say that the first available left column is represented by 1, and the last available right column is represented by 2. Available would mean we haven't covered all the letters in that column yet. So, our pattern for the column we're on would be 121212 repeating. Now, let's represent keys by the next numbers, so 3, 4, 5 3, on the first column left-to-right, would be Q 4, A and 5, Z We start on a 1 column, QAZ and type 5454, then a 2 column, PLM, and type the same. We go back to our QAZ column and type 4343, and go to the 2 column, PLM, and the same. We repeat this, so ZAZA - 5454 on QAZ MLML - 5454 on PLM AQAQ - 4343 on QAZ LPLP - 4343 on PLM QAZ and PLM become unavailable, and we move on to WSX and OKN. Then, the entire rest of the keyboard, coming in from both sides.
