Details

The patch adds the possibilty to move the cursor with shift in the other dimension. For example, if you move the cursor up and it wraps (jumps to the last row), the column is also changed (one to the left). Thus you can reach every calculator button by just keeping pressing up or down or left or right.

As of now, the button combination is only defined for Sansa e200/c200 (scroll wheel back and fwd) and only for moving up/down since that's what the wheel does in menus and lists.

Also introduced constants for the number od button rows and columns. And renamed 'global' variables for the cursor positions. m and n are too short to be a global name IMHO.
This task depends upon

The c200 has no scroll wheel - hence you would break the build for it if you don't devide the "Sansa button definitions" into two now and only enable this for scroll wheel targets. Then Ipods could have it too and maybe the c200 could use "volume up/down" instead (probably gigabeat too then?). I'm not sure I understand your description completely but I guess it's navigating the calculator "button grid" the same as it is done in minesweeper for scroll wheel targets? If so - I like the additional functionality for the targets that can have it.

Oi! Sorry, didn't know about the differences between e200 and c200. The idea is that after wrapping, the cursor ('current button') goes to another row/column.

For example: you are in (row,col)=(4,2) -> down2 -> (5,2) -> down2 -> (1,3) -> down2 (2,3) -> ... -> (5,5) -> down2 -> (1,1)

Note how the column changes when wrapping from (5,2) to (1,3).

'Down2' is a new button (action) which is added by this patch. I.e. the old 'down' action is retained (which does not change column when row wraps).

Same applies to up/left/right.

The first impulse for this patch came when I noticed that the arrow keys 'up' and 'down' don't work in e200 sim. They are mapped to wheel back/fwd. So I wanted to map them. The first idea was to make it move the cursor just up/down. But then left/right movements were not possible with the wheel. This 'double' wrapping should help in that respect.

I've written all this to help aothers to understand how and why this patch appeared.

Updated the patch so that the new buttons are only defined for Sansa e200.
