How to select multiple edit fields?

Hi,

In my user interface, users can specify a dimension, for exam m x n, then I draw a m x n table, where each element is an edit field such that users can change values in any edit field.

% Horizontal margin of the canavas
hMargin = 0.02;
% Vertical margin of the canavas
vMargin = 0.02;
% Element width 
elemWidth = min((1-2*hMargin) / n, (1-2*vMargin)/m);

% Create an edit field for each entry
for j = 1 : m
    for i = 1 : n
        pos = [hMargin+(j-1)*elemWidth 1-vMargin-i*elemWidth elemWidth elemWidth];
        e = uicontrol('Style','edit',...
                    'Units','normalized',...
                    'Position',pos);
    end
end

But sometimes, users might want to have a row with same values:

for example in the image, users will have to change the values on row 5 one by one from 0.5 to 1.

Is there a way to have something like a brush, that for the places with the same values, after modifying one edit field, the others can be simply "brushed" to have the same values? Or is there a way that users can jump between each edit field with the arrow keys (currently they always have to use a mouse to select)?

Thank you very much!

Can you post some sample code?

Hi! I have posted the sample code for creating the edit field entries.
