A previous comment from Nelson: My favorite is taking a course in Canada for my job. The work days spent in canada can be used to proarte your annual wages as foreign sourced, and you get a nice tax credit if you have some unused FTC from past years.
So if I have unused FTCs from collapsing spouse's RRSP within last 10 years and took business trips overseas last year, I can show a prorated amount of my W2 income on a general cat income 1116 and use up some of those FTCs even though I didn't pay any foreign tax in 2012?

Yes. And you prorate by days WORKED, not simply by total working days, so you can subtract vacations holidays, etc to make your percentage bigger.
After 20 years, I am severely cutting back on responses. Do not ask specifically for my help. There are a few others on this board that can answer most questions. All the best
