Correcting the logic of the hotkey modifiers for select
non-manifold. If you want it so all three modifiers are needed
(e.g. ctrl-alt-shift-MKEY) use:

if ( !(~G.qual & (LR_SHIFTKEY | LR_ALTKEY | LR_CTRLKEY)) )

instead of

if ( G.qual & (LR_SHIFTKEY | LR_ALTKEY | LR_CTRLKEY) )

(which really allows any modifier, alone or in combination, to work).
