It is possible to collapse a given bookmark with JavaScript or to close all levels of bookmarks by "walking" the bookmark tree from the bottom levels to the top level.
// the bookmark open property is not supported by Reader;
if(app.viewerType != "Reader") {
function OpenBookmark(bm, bOpen){
/*
Purpose: to Open all the bookmarks in a PDF file
Inputs: bookmark object
bookmark open property's logical value default is true
Optionally the bookmark open property can be passed as open or close
and the funciton will set bOpen parameter tot he correct logical value.
Returns: logical for sucessful completion of function;
Notes: This function can be placed in the folder level JavaScript folder and called through the JavaScript (Debugger) console or called from a batch process. It could also be added to a PDF as a document level function and executed on each opening to open all the bookmarks in the PDF.
// example of usage
OpenBookMark(this.BookmardRoot, true);
This function is recursively calls itself to work through the bookmark tree.

} // end not reader
function ToggleBookmarks() {
// toggle bookmark navigation pane value
this.pane.toUpperCase() != "B"? this.pane = "B" : this.pane = "";
return true
};
// add menu item
app.addMenuItem({
cName: "ToogleBookMarks",
cUser: "Toggle Bookmarks Pane",

cExec: "ToggleBookmarks();",
cEnable: "event.rc = (event.target != null);"
});
try{
app.removeToolButton({cName:"ToggleBookmark"});
} catch (e) {
// do nothing;
}
// add a toolbutton
app.addToolButton({
cName: "ToggleBookmark",
cExec: "ToggleBookmarks();",
cEnable: "event.rc = (event.target != null);",
cTooltext: "Toggle Bookmarks"
});
I'll let you figure out how to add the menu item or toolbar button.

Thank you so much for posting - I read the keyboard shortcuts before and assumed it meant the same as others do.
