Mahan - if you are using a MATLAB figure (which is the screen with something changing on it), you can assign a function callback to the WindowKeyPressFcn property of the figure. This callback would be called so long as the figure has focus. Try using the following code in a file saved as KeyPressFcnTest.m
function KeyPressFcnTest
close all;
h = figure;
set(h,'WindowKeyPressFcn',@KeyPressFcn);
function KeyPressFcn(~,event)
fprintf('key event is: %s\n', event.Key);
end
end
The event.Key will give you the name of the keyboard button pressed (rightarrow, leftarrow, etc.).

Does the left arrow interact with the open page on the Google Chrome browser? Please clarify what you are attempting to do.
