Are talking about figures or uifiguires? Did you create the GUI by code, GUIDE or AppDesigner? Please post the code you have tried and explain, which problems it has. Then it is much easier to suggest a solution. The less the readers have to guess, the more likely suggestions match your problem.
The EventData should allow you to distinguish the mouse keys.

sorry for not including that,
w=9;
h=9;
fig=figure;
panel = uipanel(fig, ...
'Units', 'normalized', ...
'Position', [0.1, 0.1, 0.7, 0.7]);
for iR=1:w
for iC = 1:h
button(iR, iC) = uicontrol(panel, ...
'Style', 'pushbutton', ...
'Units', 'normalized', ...
'Position', [(iC-1)*1/fS(2), 1-iR*1/fS(1), 1/fS(2), 1/fS(1)], ...
'String', ' ', ...
'Callback', @buttonPushed, ...
'Tag', ' ');
end
end
and i tried this. there is error:Unrecognized property SelectionType for class UIControl. i see, where is the problem, but i dont know how to solve it.
function buttonPushed(hObj, ~)
f=get(hObj, 'SelectionType')
if f=='alt'
hObj.String = sprintf('!')
else
if hObj.Tag == 'bom'
hObj.String=sprintf('bomb');
hObj.BackgroundColor='red';
else
hObj.String=hObj.Tag;
hObj.BackgroundColor=[0.3010 0.7450 0.9330];
end
end
end

Comparing char vectors by == fails, if the number of characters is not equal.
'123' == 'abc' % Working
'1234' == '0' % Working, because 1 variable is a scalar
'12' == 'abc' % error
Use strcmp instead.
The SelectionType is a property of the figure:
function buttonPushed(hObj, ~)
hFig = ancestor(hObj, 'figure');
Selection = get(hFig, 'SelectionType')
if strcmp(Selection, 'alt')
...
end
