I don't know if these are techniques rather then hotkeys, but I actively use the following (Note: I'm not really a big fan of IDEs, but use them professionally to conform to my work environment and Eclipse, while somewhat bloated, is very pleasant and gets better with every milestone). Debugging: Learn the hotkeys for stepping in (F5) over (F6) out (F7) and continuing (F8), I get super frustrated watching people click on the icons. Really helped the transition from debugging with the likes of gdb. Conditional Breakpoints are a revelation. Remote Debugging is great (I've been able to debug remote java processes, Lotus Notes (yuck) instances, Eclipse workbenches (for plugin development), Remote Perl Server Code (with E-P-I-C and Padwalker)... Eclipse's debugger interface is amazing. Text Editing w/ Java and CDT: CTRL+W : close active editor CTRL + Space : Autocomplete (mentioned earlier) CTRL + SHIFT + O : Organize Imports (Finds classes that should be imported, removes excessive imports, etc...probably one of the most justifiable reasons to use an IDE for Java development) ALT + SHIFT + J: Add Javadoc in context CTRL + SHIFT + G : Does a search on the highlighted text's context (i.e.) a method name to show where it is used. F3 : Navigates to selected context (Method, class, variable, etc.) CTRL+SHIFT+T : Presents Dialog for searching through Types (works in most perspectives), i.e.: Searching for a particular java class. F4: Show the Type Hierarchy (subclass/superclass information) Import & Export wizards are your friend (Creating java jars, exporting projects to archived zips). Eclipse can be used to track history (kind of like your own personal lazy SCM). If you make a mistake you can right click on a file and perform "Replace With > Local History..." (this may need to be enabled in preferences). You can also Compare to history well. Tasks : The 'Mylyn' plugin is great for GTD and Task management. I was a bit apprehensive at first, but it's pretty incredible, especially if you are a nut about keeping organized. You can create tasks, and assign your current work to it, and it will track and remember context (what classes you used) as you work on that task. Mylyn also interfaces with Bug Trackers like Bugzilla and JIRA.
