Eclipse Tool Tip #4: Key Assist
Every once in a while you need an assist, well, Eclipse gives it to you. Go to Help > Key Assist to open a dialog containing a lot of short cuts to different Eclipse functionality such as Content Assist (ctrl+space) to Word Complete (alt+/). The hot key short cuts I use the most are ctrl+shift+r to open a resource, ctrl+shift+t to open a type, and ctrl+t to display the type hierarchy, ctrl+shift+f for code format and ctrl+space for content assists amonst others. But if you forget all other hot keys, just remember ctrl+shift+l to open the Key Assist.
