Best Aptana Studio (Eclipse) Shortcuts

The following is a list of shortcuts that I use most in Eclipse environments but can't seem to find all in one place anywhere else on the web. Note that I experimented with these using the Aptana Studio plugin but most of them should work with any version of Eclipse.

Shortcut	Action
ALT + Up/Down	Move lines(2) up/down
CTRL + ALT + Up/Down	Duplicate lines(2) up/down
CTRL + / or CTRL + 7	Toggle block comment
CTRL (+ Shift) + Tab	Switch to next/previous editor
CTRL + w	Close tab
CTRL + d	Delete line(s)
CTRL + l	Go to to line
CTRL + Space	Content assist
ALT + /	Word completion
