some computer questions

I've been asking a few questions here recently. so here's one more from the vaults:

Is there a internet search engine that pays attention to punctuation marks?

I was also going to ask how to tick GUI checkboxes from the keyboard as I've been trying to use the keyboard more (and one-handed, and left-handed, and mousing reverse-grip left-handed, too. Actually, I'm trying to get past even that now, to just keeping on the flow and feeling both hands as much as possible), but I figured it out: once you TAB onto one, SPACEBAR does the trick.
