Shift/ctrl mouse buttons are not available via GPR in SR10.1. 
The borrow mode X server uses function keys for shift, control, and 
meta - not the actual shift or control keys.

The DM does define shift/control mouse buttons so you could use 
pad_$def_pfk to redefine M1S, M1C, etc. The application would then
have to wait on both gpr input and stdin.

Shift/control mouse buttons will be available with the GPR that 
ships with DOMAIN/X11 V1.1. This is the "share-mode" X11 for sr10.1. 
DOMAIN/X11 V1.1 is currently in beta and we expect FCS in a few months. 
In addition, we will be merging DOMAIN/X11 into the base Apollo 
software in a future release.
