This must be dumbest question ever asked, but...
When I ask help.search("tcltk"), I get a reference to tcltk-package.
When I ask help("tcltk-package"), I get "rtfm(s) in 'R_HOME/Tcl/doc'".
But then when I ask help.search("R_HOME"), I get nothing.
Is something missing here in those help pages?
"R_HOME" is a short form for "the directory where you installed R". This is referring you to a directory on your system that holds documentation that's outside of R's help system.
Note that R_HOME corresponds to the R.home() path so you can do this on Windows (and the analogous operations on other platforms):
setwd(file.path(R.home(), "Tcl", "doc")) dir()
[1] "tcl84.cnt" "tcl84.GID" "TCL84.HLP" "tk84.cnt" "TK84.HLP"
system("cmd /c start TCL84.HLP")
system("cmd /c start TK84.HLP")
