As you may well have guessed this is a 'test' from a bigger appliation.
I called $t->curselection from the brwscmd because I alsowant to be able to select more than one cell using the
windows explorer techique where with the left hand mouse key
1. the Ctrl key allows you to select a number of cells;
2. the Shift key allows you to select a rnge of cells.
I have just looked in the documentation for the tablematrix.In the Default Bindings section it says that "The left, right, up and down arrows move the active cell".Therefore I wonder if there is problem with the basic table matrix code.
