[Windows 10 Edition issue]

Pressing Alt + Space (or Space + Alt) triggers the Windows 10 shortcut to open the window menu of programs. When playing Minecraft Windows 10 edition, it pauses the game, which is problematic for players who use alt as their sneak key.

Another issue with using Alt as the sneak key is if you hold Alt and:

• 2 other keys or
• Shift or
• Control
  then the player is "locked" into sneaking unless Alt is pressed again.

This leaves alt as an unusable key for sneaking (or any movement related action).
