Hi,
I have a number of different x,y lines using different detection methods on an image.I want Matlab to save a specific line depending on the key I press. So if I press 1 for example, Matlab saves detection method a, if I press 2 Matlab saves detection b. I have investigated KeyPressFcn, but this doesn't work. Are there any simple functions I can use that can allow me to do this?
Many thanks in advance, John

doc KeyPressFcn
should take you straight to the documentation of this property for a figure.

What exactly are "different x,y lines"? What does "saving a line" mean? What is "detection method a"?
Of course the KeyPressFcn is the solution. So please post your code. You can find many examples if you ask an internet search engine for "Matlab KeyPressFcn". "No documentation exists" is simply wrong.
Please post the current code and explain explicitly, what "doesn't work" means. Do you get an error message?

You can refer to the following documentation : https://www.mathworks.com/help/matlab/ref/matlab.ui.figure-properties.html
Please scroll down to Keyboard Callbacks
For another function you can also refer to: https://www.mathworks.com/help/matlab/ref/waitforbuttonpress.html?searchHighlight=waitforbuttonpress&s_tid=doc_srchtitle
and do the required action based on the value of the key pressed.
