Pragmatic Dave talks about being an Emacs guy that made the switch to Eclipse.

I can identify with that. I’ve downloaded most of my brain into Emacs macros so that I find it difficult to survive without a fully functional Emacs available. However, when it comes to editting Java code, it is tough to beat Eclipse (or IntelliJ/IDEA, or any number of similar IDEs). Although I still like Emacs for pure code/text entry, Eclipse really shines when you need to do browsing, refactoring or even CVS integration.

This is one gotcha, however. Whenever I save a file in Emacs, I hit

• Control-A (goto the beginning of the line), then
• Control-X Control-S (save a file).

Over the years I have learned that frequent saving is a good thing, and I perform that sequence of keystrokes without even thinking.

However, that same key combination in Eclipse performs …

• Control-A (select all)
• Control-X (cut selection)
• Control-S (save file)

Oops! Thankfully, Control-Z (undo) forgives all sins.
