Hello, is it possible to detect pressing of modifier keys (Ctrl, Alt, Shift) or Home, Pgdn etc. in GUI? I use command get(gcf,'CurrentCharacter'), but for mentioned keys I get empty variable.
Thank you

You can catch such keys in the WindowKeypressFcn. This will help you to identify the names of the pressed keys:
FigH = figure
set(FigH, 'WindowKeyPressFcn', @KeyPress)
function KeyPress(Source, EventData)
disp(EventData)
Another idea is to use the (still undocumented?) "CurrentKey" and "CurrentModifier" properties of the FIGURE.
