I've used DBeaver for a while now, and there are a lot of things that I really like about it, especially over SQuirreL.
On my windows machine, the home/end keys work perfectly. However, using my microsoft keyboard plugged into my mac, the home/end keys have stopped working. I instead have to use command left and command right.
I know this isn't a system wide thing, as my text editor (sublime text 3) supports the home/end keys on my mac.
It's a small thing, but if I save 1 second here and there, I'm way more productive overall.
