*RMB stands for Right Mouse Button
*LMB stands for Left Mouse Button
*MMB stands for Middle Mouse Button

*Text within brackets < > indicate a keyboard command: i.e. <CTRL+t> indicates you should use the keyboard command control and "t" to initiate a command.

*All commands are case sensitive in maya so a "t" is different from a "T". A capital "T" as in the command <CTRL+T> indicates you should press Control, Shift and "t" at the same time.
