On the Subject of Not Coordinates

Column second or row second?

Picture a 9×9 grid. Determine the positions on the grid that are indicated by the module.

Each display corresponds to a unique position in the grid.
Three of the positions lie on three vertices of a square within the grid. Submit the three displays that correspond to those positions.

Use the left and right arrows to cycle through the list of displays and the middle button to submit the current display.

Grid position formats

[x,y]Column, then row; top-left is [0,0].
letter numberColumn, then row; top-left is A1.
<x, y>Row, then column; top-left is <0, 0>.
x, yRow, then column; top-left is 1, 1.
(x,y)Column, then row; bottom-left is (0,0).
letter-numberColumn, then row; bottom-left is A-1.
x, yRow, then column; bottom-left is “0, 0”.
x/yRow, then column; bottom-left is 1/1.
[x]Cell number in scanline order, top-left is [0].
xthCell number in scanline order, top-left is 1st.
#xCell number in Cartesian order, bottom-left is #1.
四十七Cell number in Chinese reading order, top-right is 一.
(The example shown is the number 47.)
x cardinal, y cardinalThe number of spaces, in the specified direction(s), from the centre of the grid.
"centre" is displayed if the corresponding position is the centre of the grid.
cardinal from cardinalThe second cardinal is the relative position of the 3×3 subgrid from the centre.
The first cardinal is the relative position of the cell from the centre of the subgrid.
If only one cardinal is displayed, the cell is at the centre of the displayed subgrid.

Once all three correct displays have been submitted, the display will change to one of the shapes in the grid below.

Each of the following actions toggles the display in one of the following ways, wrapping around the edges of the grid/subgrids:

Pressing left when the number of seconds left on the timer is even-
Pressing left when the number of seconds left on the timer is odd-
Pressing right when the number of seconds left on the timer is even-
Pressing right when the number of seconds left on the timer is odd-
-moves to the cell in same position in the subgrid to its left/right.
-moves to the cell in same position in the subgrid to its top/bottom.
-moves to the cell to its left/right within the current subgrid.
-moves to the cell to its top/bottom within the current subgrid.

Navigate to the cell where the fourth vertex of the square, that was not originally displayed, is located and submit the displayed shape.

Note: Some of the cells cause the display to glitch, obscuring the left and/or right side of the displayed shape.
