Hi Rayle
the following only captures one keystroke at a time, but as long as the figure is active, no system shortcuts are executed, including shift F10, try it.
1.
Let me show you how to use figure to capture keystrokes
clear all;close all;clc
a='0';b='0'
S.fh = figure( 'units','pixels',...
'position',[500 500 200 260],...
'menubar','none','name','move_fig',...
'numbertitle','off','resize','off',...
'keypressfcn',@f_capturekeystroke,...
'CloseRequestFcn',@f_closecq);
S.tx = uicontrol('style','text',...
'units','pixels',...
'position',[60 120 80 20],...
'fontweight','bold');
guidata(S.fh,S)
function f_capturekeystroke(H,E)
S2 = guidata(H);
P = get(S2.fh,'position');
set(S2.tx,'string',E.Key)
assignin('base','a',E.Key)
evalin('base','b=[b a]')
end
function f_closecq(src,callbackdata)
selection = questdlg('Close This Figure?','Close Request Function','Yes','No','Yes');
switch selection
case 'Yes'
S.fh.WindowSyle='normal'
delete(gcf)
case 'No'
return
end
end
.

Regarding the crux of the query
' .. to detect a keypress and initiate action based on what key was pressed and whether or not a given different key had been pressed first .. '
the variable b contains the log of all keystrokes, sequentially logged, so one can catch combinations like ctrl+S
One can build a 2 characters window and with a switch discern any string that should trigger desired events.

For the mouse capture, a start point for your development could be Rodney Thomson example, one of many examples compiled in a bundle available in the File Exchange to start learning GUI development, but also directly available here
[EDITED, copy righted code removed]
.
test call
.
t = linspace(-5,5);
y = sinc(t);
f = figure;
plot(t, y, 'r');
set(f, 'WindowButtonMotionFcn', @(obj, event)cursorLocation(obj, event, 'BottomLeft', ' X: %.3f\n Y: %.3f', 'r'))
.

May be you can get all shortcuts overloaded with Java, the solution may be in the following reference:
