Honestly I would just learn the shortcuts for selections. You will work faster than any toolbar.
I don't think I've used the selection mode tool bar in 10yrs or more, it's only a handful of things
to remember.

Not an answer to your question, but more a suggestion for a better workflow.

Space+1 = Perspective viewport.
Space+2 = Top viewport.
Space+3 = Front viewport.
Space+4 = Right viewport.
Space+5 = UV viewport.

S to enter selection mode,
2 = points
3 = edges
4 = polys

t = transalte
r = rotate
e = scale
y = cycles through those, and if at OBJ level will cycle combo manipulators.

m = will cycle through transform space modes, local, object, world, view

It's because negative jitter is where particle integration is actually correct.
If the emitter moves, it's no issue, but I'd highly recommend watching and implementing Ben's
integrated particle setup, say goodbye to bad or stepped emission on moving objects forever.

MPM is running on openCL, it's very likely your GPU driver version could be the culprit.
