To add a new view link:

create makeXXXSpt(), makeXXXHelp()

Above getLinkIndex() in jcontrol.js, add a new xxxIndex variable and number.

In getLinkIndex() in jcontrol.js, add a new if: return.

currentView ??



// -------------------------------------------------------------------------
If in preContacts, method for canceling it:
	selectMode = "";

When adding something (or removing it) from the current view
(e.g. toFind, target * marks for Contacts)
the code to toggle the addition should be in doMolViewSpt()
(see instances of doMolViewSpt("") in jcontrol.js and top.js)

consider also reDisplay("", "")
	which calls doMolViewSpt()


// -------------------------------------------------------------------------
makeViewLink() (jcontrol.js)

puts the NAME of a script (variable name or function name) in viewLinkSptName[],
and puts the NAME of the help (variable name or function name)
  in viewLinkHelpName[].

N.B. the help function often does some crucial settings.

------------------
doViewLink() (jcontrol.js) is executed
	when the link is clicked, 
	called with the matching linkIndex.

It prepares for the new view.

then shows help: showHelp2(viewLinkHelpName[lnum])

then does some initialization in the displayed help.

If the view link has no script (more views, troubleshooting) it does
    cancelCenteringNoHelp(); // sends script set picking on
    selectMode = ""; // in doViewLink()

If it does have a script
  top.showNonStandardResidues = false;
  top.hideMode = "";
and if not preContacts
  top.selectMode = "";

Next BUTTONS are forced up/down as needed for the new view.

It records in currentView the new script NAME.
 currentView = viewLinkSptName[lnum] = e.g. "rocketSpt", "makeChargeSpt()"
or if there is no script, an identifier such as "Ends" or "moreViews".

Does some final preparations,

Turns centering off (unless we're centering)
    top.centerMode = false;

finally doMolViewSpt( eval( viewLinkSptName[] ))

------------------
doMolViewSpt() (scripts.js)

inserts makeHideSpt()

regenerates dots as needed

if not uncertainty, resets default hoverSpt and clears top right echo.

scriptToJmol(spt)

------------------
scriptToJmol() (top.js)

does set picking ident if centering was in effect but not now.

does makeMarkContactsTargetSpt()

does makeLabelSSBondsSpt()

does S-,X,? labeling

marks broken ends (or clears empty baskets/gapmeshes) according to markBrokenEnds boolean.

adds halos as needed

if debugging, showSptInWindow(spt)

unchangedScriptToJmol()
