That should be

Tool :=
TStandardCodeTool(CodeToolBoss.GetCodeToolForSource(node.CodePos.Code,
true, false));
if Tool=nil then exit;

An "identifier" is simply a valid pascal identifier (starting
with a letter, followed by some letters and numbers).
A 'keyword' is context sensitive. 
For example when doing identifier completion the following 'function'
is an identifier:

i:=function|

I wrote an example in codebrowser.pas:
function TCodeBrowserView.GetCodeHelp
