Menu Specials and Grab shorcut for maya interface??

Im using Maya interface, and i find myself trying to figure it out how to use the grab feature and how to display the specials menu. I cant even find em on the input list so i can re-assign shorcuts.

Also, how can i activate the auto-extrude??? you know, when you press CTRL+click (that automatically extrudes and rotates).

Halp! Thanks in advance.

Ok, i figured it out. Just in case someone want to know, the specials menu pop ups using CTRL+Right Mouse Button. Also, and i didnt know this (or i completely forgot), pressing space bar shows a menu where you can see the shorcuts to the special menu and other “hidden” things. From there, you can also get a shorcut for the Grab feature.
