I have to use < and > as one of my application use this 2 keys. However when I select by pressing Shift < and Shift >, it registered as Shift , and Shift . . It seems not working as it should be < and > . Is that any way to fix it or it may be I missed out something?

But Shift + , is equal to <

Not sure what you mean.

 

I think this is once again the issue with a keyboard layout different than US QWERTY. @fencingcoach you probably have the < and > on different keys on your physical keyboard than in the GUI. Just look at your keyboard how to write them manually (what keys you need to press to get them). In the GUI don't look at symbols on virtual keyboard but at what position they are (which key row and order in a row) and record that key or key combination.

If you still don't understand and don't know what to do then please tell me what keyboard layout you have selected in the OS.
