MED: Matrix Editor

This description is from matrixedit.wp34s:
Code:
/*
 *  Interactive editor for matrices.
 *  Start the editor with a matrix descriptor in X.
 *  Use the arrow keys to navigate:
 *    up/down: previous/next column
 *    f-up/f-down: previous/next row
 *  Type a digit to enter a number. This will suspend
 *  the progrom. R/S will enter X at the current row/column.
 *  XEQ RCL restores the present value to X if you decide
 *  not to change the cell. Press R/S to continue.
 *
 *  Some hot keys:
 *   A will start over at (1,1).
 *     When used outside the editor you will need to specifiy
 *     a new descriptor first.
 *   B (labeled 1/x) will call M[^-1] on the matrix.
 *   C continues at the last position.
 *   D computes and displays the determinant. R/S or C continue.
 *
 *  We need a few registers for internal use and therefore 
 *  set the stacksize to 4 to free registers A to D.
 *  Press <- to restore the mode and exit the editor.
 *  Double precision mode will always be reset!
 *
 *  Register usage:
 *   A - Matrix descriptor
 *   B - Current register
 *   D - Old setup mode
 *   I, J - Row and column
 *   K last key pressed
 *
 *  Flags:
 *   A - Controls big "=" sign
 *   00 - Shift state
 *
 *  Fixed labels:
 *   A, 11 - Start over with new matrix ('A'gain)
 *   B, 12 - Compute the inverse ('1/x')
 *   C     - Continue with current matrix ('C'ontinue)
 *   14, D - Compute the determinant ('D'eterminant)
 *   22    - [RCL] recalls current matrix element
 *   24    - [f] toggles navigation from horizontal to vertical
 *   31    - [ENTER^] (same as recall)
 *   35    - [<-] Backspace to exit the editor
 *   51    - [^] Navigation up/left
 *   61    - [v] Navigation down/right
 */

Who would have guessed? The best documentation really is in the source code...
