In eclipse , you can view origin code pressing SHIFT; but in IDEA, I must press CTRL + MOUSE DOWN to another page to look it. Can IDEA like Eclipse?
In IntelliJ, it called Quick Definition. It is bound to Alt+Space or Cmd+Y in my environment, however, it would be different depending on keymap.
Open your Preferences dialog > Keymap and find quick definition in the right pane of the dialog. You will be able to see the key binding for that.

I want to replace all instances of Foo.bar() with Foo across all files in my workspace in eclipse. Is there a way of doing this?
When you do a text-based search in eclipse (using the flashlight button at the top of the screen and selecting the right tab) there's a "Replace..." button at the bottom of the dialog. Press that, instead of search, and you can do a global find and replace.
Alternatively, you can use the refactoring feature to change it to something else.
