When pressing right alt key together with ctrl key, it is ignored in the resulting shortcut

[RaymondLim]

1. Add Czech keyboard layout.
2. Launch Brackets and switch keyboard layout to Czech.
3. Press right Alt key and D key. You will see a non-English character.
4. Now press right Alt key, Ctrl key and D key.

Result: Current line is duplicated. If you look in the menus, you will see Ctrl-D under Edit menu but no Ctrl-Alt-D in any menu. So AltGr key is totally ignored.

Expected: Ignore Ctrl key and input the non-English character like NotePad++ does. Or run the command assigned to Ctrl-Alt-D as in Visual Studio if the Ctrl key is pressed first. In VS if the AltGr key is pressed first, it ignores the Ctrl key and input the non-English character.

on Linux with czech keyboard Brackets behaves the same (Ubuntu 14.04). Just duplicates the line
