I use XCode and other apps frequently.
Suddenly 3 days ago, some of the shortcuts on my Macbook pro stopped working
Namely the Cmd + Shift + O, Cmd + Shift + R, Cmd + Shift + W when the Cmd and Shift are on the left side of the keyboard, when they are on the right side of the keyboard it works just fine.
On my other mac computer, they also work just fine.
On an external keyboard they also work just fine
Cmd + any combo works just fine and Shift + any letter gives upper case letter as expected
Why isn't the combination left side Cmd + Shift + anything work anymore ?
Just to be clear, when I click that combination, the computer recognizes it as Cmd + anything , and does not see that I also pressed Shift

First, check System Preferences > Keyboard > Keyboard Shortcuts to see if cmd-shift-N has been mapped to anything. Be sure to check all the system categories as well as Application Shortcuts > All Applications.
If that doesn't reveal the culprit, you might want to look to see if you have any "Input Manager hacks" installed. These are third-party tools that use a skanky method to modify the behavior of the system and other apps. Some of the best known Input Manager hacks include SIMBL (and tools that use SIMBL, such as Afloat) and APE (Unsanity's Application Enhancer, and related "Haxies"). If you find any input manager hacks, remove them according to their instructions.
