during debugging, I need to complete a for loop and continue debugging line by line; when I press shift+F11 it gets out of debugging mode altogether

The only thing I can think of to do this is to set an if condition on a variable that you would modify while debugging. E.g:
a = false;
for ii = 1:10;
disp('hello world');
if a;
break
end
end
disp('It''s Thursday!');
So when you want to escape, set a to true from the command line and it will exit the next time the if-condition is hit.
This is unless you wanted the for-loop to complete. If that is the case, just set a breakpoint after the for-loop and click continue.

Put your cursor on the first executable line after the loop, and use the mouse menu item to execute until cursor. (Unfortunately there is no known shortcut key for that.)

You can manually set the loop variable to meet the loop ending condition.

That will not work for a "for" loop. "for" ignores any user changes to the loop index variable and uses its own internal knowledge of how far it has proceeded.

This will not work. Any changes made to the for-loop variable are not stored at the end of the loop iteration.
Curiously, break is not working either.

Thanks Walter and Sean, I never realize this.
