Feature request: Don't remove space in number pad

Have an option to not remove preceding space when using Number Pad entry to put a period in.

This would be very useful for math and in some cases, IP address abbreviations ("The router is .1 and the DNS server is .2")

I love the behavior of the period key in the normal text entry, but the number pad could invite expectation of different behavior. To expand on this idea, maybe other "autocorrect" features might be disabled in the Number Pad mode.
