It is better to send Chimera questions to chimera-users at cgl.ucsf.edu  
(instead of to me directly) and include something meaningful in the  
"Subject" line.  Also, you can use "Help... Search Documentation" in  
the Chimera menu to look up information by keyword.

(1) menu "Select... Zone."  You can also specify zones in commands.

(2) That is up to your own scientific judgement. As mentioned in an  
earlier reply, the minimization capabilities in Chimera are rather  

(3) Chimera does not do docking calculations.  You can move two  
structures together by hand... of course that is only approximate.

However, Chimera does have tools that are related to docking:
"Dock Prep" for preparing structures for docking or other calculations  
(with other programs outside of Chimera) and "ViewDock" for looking at  
docking results output by other programs, mainly DOCK.

Here is the Web site for DOCK.
They also have tutorials:
