Shift-Up/Down for multi-word shiftable terms

[schittli]

Good morning
Thank you very much for this great Plugin!, it has a kind of magic :-)

I tried to use Shifter with Strings which contains a space, e.g:
|todo Task:|todo Bug:|todo Question:|
This would allow to quickly change todo-Comments.

Shifter works with those terms if one selects the existing string and then use Shifter, otherwise, it does not detect the shiftable terms.

It would be great if Shifter could detect Multi-Word shiftable terms... unfortunately, I guess this could be really tricky.
