[Chimera-users] Grouping of bonds/atoms

[Elaine Meng]

Hi Thomas,
There isn't a keyboard shortcut except selection undo (left arrow,  
only remembers one previous state), but if I understand you correctly  
there are some possibilities for making your life easier:

(a) you can name a selection with "Select... Name Selection" (or  
command namesel) and then later simply use that name in commands or re- 
select it with "Select... Named Selections... [name]"
<http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/namesel.html>

(b) if it is something that can be described with a command-line atom  
specification string, you can avoid selecting altogether and just  
alias the specification.  The alias can then be used in subsequent  
commands.

For example:

alias inhibitor :/isHet & ~ solvent
show inhibitor
alias sheetset :25-38,127-136,145-170,196-212
ribbon sheetset
alias sheeta sheetset & :.a
color dodger blue sheeta

Thanks for the holiday wishes -- Merry Christmas to you too!
