Lightroom 3 ~ Move photos from one catalog to another, existing catalog? Not "export as new catalog"
After consulting the interwebs and the Adobe site and a book about Lightroom 3, I remain confused about how to quickly and easily get photos from one existing catalog to a different catalog, since LR doesn't allow one (for its own arcane reasons, I assume) to have more than one catalog open at once.
Say I've got a Quick Collection of stuff I previously imported into "Catalog X" when it really belongs in "Catalog Y." What is the best way to get those photos into Catalog Y? Exporting this Quick Collection as a new catalog; closing down Catalog X; bringing up Catalog Y; running an import dialogue to import that Quick Collection... well, that seems pretty ridiculous. I assume I'm missing something obvious. Anyone know what the command is?
Also, if anyone can direct me to the Lightroom 3 discussions, as the search function here seems pretty rudimentary (e.g. put "lightroom 3" in the search box and it will bring up dozens of hits for "lightroom 4.3"), that'd be awesome... thanks...
