<p>Hello,<br>
<br>
IMHO, the only way to trap a keypress and get the ascii (?)
code is to use the event_handler callback of a figure :<br>
<br>
function handler(x,y,ibut)<br>
//<br>
endfunction<br>
<br>
f=gcf();<br>
f.event_handler='handler';<br>
f.event_handle_enable='on';<br>
<br>
On my computer, I have the following mapping <br>
<br>
left arrow pressed : ibut=37 (released=-37)<br>
up arrow : 38<br>
right arrow 39<br>
down arrow 40<br>
<br>
The problem is that you need to have a figure opened, and
that this figure must have the focus.<br>
<br>

<p>Hi Samuel,<br>
ASCII representation of up, down etc. would help me if I
knew a Scilab<br>
command which puts the ascii value into a variable.
input() is definitely<br>
unable to do so.<br>
