I would like to be able to increase a number by pressing on the right arrow key, and decrease it by pressing on the left arrow key. I would like it to increase or decrease by 10 each time starting at 10: 10, 20, 30, 40,.....
Thank you!

Create a figure and configure a Windowkeypressfcn callback that gets the figure CurrentKey property and decides what to do.
Or use one of the File Exchange contributions to wait for a key to be pressed.
Also if you have a slider and the slider has focus then the uparrow and right arrow increase the value by sliderstep and the down arrow and left arrow decrease by sliderstep
