[FIX] jQuery.sap.global: open the TechnicalInfo only when left 'alt' is pressed
[FIX] jQuery.sap.global: open the TechnicalInfo only when left 'alt' is pressed

- The right 'alt' key is mapped to 'alt' + 'ctrl' on windows under some
  languages, for example German and Polish. This makes the key combination left
  'alt' + 'shift' + P|S open the TechnicalInfo which isn't expected

- this fix checks the 'location' property on the key event to check whether the
  left 'alt' is pressed and only then opens the TechnicalInfo
