You can achieve this by interfacing operating system functions. 
If your target is windows you can take a look at my ScrollLocker 
project (https://github.com/PaulFreund/ScrollLocker). It is 
written in D and uses SetWindowsHookEx and WH_KEYBOARD_LL (low 
level keyboard hook) to capture key strokes (see helper/hooks.d). 
There should be similiar facilitys in other OS as well.

It should also be possible to get certain combinations in the 
cmd/shell but I don't know how.
