Our input search fields stops propagation of keyup event for some special keys (for example, Command key on Mac or Ctrl on PC, but they should not do this.
This happens because inside openmrsSearch.js we have .keyup() handler for search field, which explicity stops event propagation in case of Windows (kc = 17, lines 251, 263-265 of that file):
in case of Mac (kc = 91, lines 277-285):
The fix seems to be pretty simple. Actually it's only 2 lines. All that's need is to change return false; to return true; within openmrsSearch.js inside snapshots given above.
