Interactive features such as "KeyPressFcn" are not yet supported for App Designer UI figures. For a list of features that are supported you can refer to the following link:
As a workaround, if you need to use any of the features that are not supported, you can use traditional figures inside the App Designer. Note that these figures will not be embedded inside the app. It will instead appear as a popped-out figure.
You can setup your App Designer code to include a button, which when pressed opens up a new traditional figure. For this new figure you can then define your "KeyPressFcn" or any other figure callback functions. Here is a small example of using the button-pushed callback function to generate a new traditional figure for which you can then define the "KeyPressFcn".
% Button pushed function: Button
function ButtonPushed(app, event)
figure('KeyPressFcn', @KeyFcn, 'Name', 'Key Press Demo'); % new traditional figure with interactive features
plot(1:100);
function KeyFcn(~, ~)
plot(100:-1:1);
end
end

As of 2018b, App Designer supports keyboard and mouse callbacks.
From the 2018b release notes:
"Figure Interactions: Create apps with custom mouse and keyboard interactions using figures created with the uifigure function"
