I've been using Visual Studio for about 6 years now, which is enough time to know most useful keyboard shortcuts and little features. I recently had to switch to Eclipse and java for school, and now I'm constantly searching for the right keys to press.

I have searched around for a definitve guide on this, but I couldn't find any. Here's what I want to know:

1. For any feature in Visual Studio, what is the equivalent feature in Eclipse called and what is it's default keyboard shortcut?
2. Are there any things that work very differently in Eclipse, that one might misunderstand or do wrong at first when switching?
3. Are there features in Visual Studio that Eclipse does not have, and is there a workaround?

I hope we can create a guide to make life easier for future developers that have to make this switch. You can answer any of the three questions above (no need to do all three), and multiple per answer if you want. I can't mark questions as community wiki anymore, but I do think that's appropriate here.
