Help my wrists deal with Eclipse

My hands hurt; is there an Eclipse IDE plugin that does text completion like NetBeans' ctrl-K or pressing escape in TextMate? In my current job I have to use the Eclipse IDE for standardisation reasons. I previously used NetBeans and came to completely rely on the ctrl-K / ctrl-L shortcuts, which search the text before/ahead for words that match the word you're currently writing.

Example: I write
System.out.println("I am Nathanael van Bendensteck. Like all Bend

and then want a command that completes that "Bend" to "Bendensteck". Which is different from normal code completion. It doesn't understand about Java, but simply searches back through the text till it finds a matching token.

In NetBeans, this is ctrl-K, in TextMate it's the escape key. In Eclipse it doesn't exist. My wrists hurt, and since I don't know what the feature would be called, I can't search for an Eclipse plugin that provides it.

Do you know of such a thing? My wrists would be very grateful.

Ruby code completion in Emacs, Intellisense-style?

Rcodetools, possibly in conjunction with Icicles, seems like it should be the bee's knees for doing Ruby code completion in Emacs. I need help getting it to actually work. Does anyone have this working properly? Could you talk me through it in baby steps? The existing documentation seems rather sparse, and assumes you're already quite proficient in Emacs lisp.

I did manage at one point to get as far as actually having rcodetools do some completion, but it behaves weirdly. For example, if I'm in an empty buffer and type 42. and execute rct-complete-symbol, it happily obliges and gives me all the methods available to an Integer. But suppose instead I type

def foo 42. end
and, with point after 42., execute rct-complete-symbol, then it tells me no completions are found. What gives?

Anyway - any help greatly appreciated. I greatly miss IntelliSense from Ruby in Visual Studio now that I'm on a Mac full time, and I'm really hoping emacs can do at least some of what VS does.
