With all the great tools being added, it's a bit of a surprise to me that greater control of negative keywords haven't been among the more highly prioritized changes... ability to import/export a list, ability to assign a set of global negative keywords to an account, negative keyword stats (how many ads were blocked?), etc.
1. If you start selecting text with the first keyword on the first line, you'll end up with some/all of the words on the first line with leading spaces. To prevent that, I start selecting text at the line above where it says, "select all."
2. If some of your negative keywords have quotes (") around them, they'll disappear when you paste into Excel. This seems to work differently depending on the browser you're using. I haven't figured out an easy workaround for Firefox (my preferred browser), so I use IE for this operation. After copying the keywords (and line above per #1) paste (NOT special) into Excel. By not using paste/special, it'll look funky but should give you four columns. Now, in Excel highlight the funky looking keywords you just copied in (sans the first line which contains the "select all" text) and paste/special/values to a clean part of the spreadsheet. You should end up with four non-funky looking columns of keywords with double quotes preserved.
I suspect it's not a coincidence that we just went through this over the weekend as we began our exodus from AdWords in earnest following the mayhem created by the recent "Quality Score" changes. I hope we can help each other with additional tips on making the transition to adCenter, Yahoo, Ask, Kanoodle, etc. easier.
I couldn't see an obvious way, looking through the menus. And in the AdWords web interface (not the software), there seems to be no way to easily duplicate campaigns or ad groups to my knowledge (in the ad group case, short of doing it manually using the keyword & ad text copy tool; but this is slow and buggy and often the copied keywords don't appear in the new group in my experience).
When creating a new campaign using the web interface, it has an option to let you copy settings from another campaign, but only copies ONE ad group (the first listed), and only its settings and ad text. I don't think it even copies over the keywords.
If you try to use the keyword copy tool and specify more than one ad group at a time, it errors out with the message that multiple ad group copying is not supported at this time. I thought the AdWords Editor would allow more flexibility than these hindrances of the web interface, but perhaps not. My goal is to duplicate entire campaigns, each having multiple ad groups.
This allows you to move or copy all the keywords and, optionally, the ads themselves from one AdGroup to another. Note that using the tool will trigger an editorial review. Hope this helps.
