Redirect link to a page with a title different from the label on the link:

 proc --> {label target} {
    return "\[%$label|showpage [list $target]%\]"
 }

Usage:

A better solution :

 # Create a button
 proc -> {name} {
     return "\[%$name |goToExecution $name%\]"
 }
 
 proc goToExecution {args} {
     set prg ""
     set extension [file extension $args]

     switch -regexp $extension {
         ".doc"   { set prg "C:/Program Files/Microsoft Office/Office/WINWORD.EXE"}
         ".htm*"  { set prg "C:/Program Files/Plus!/Microsoft Internet/IEXPLORE.EXE"}
         ".pdf"   { set prg "C:/Program Files/Adobe/Acrobat 5.0/Reader/AcroRd32.exe"}
         ".tcl"   { set prg "C:Program Files/UltraEdit/UEDIT32.EXE"}
         default  {return}
     }
     exec $prg "$args" &
 }

Usage in a page of my Notebook for edit or view something :
 [@ -> http://mini.net/tcl @]
 [@ -> http://mini.net/tcl/Notebook%20App%20-%20User%20Code%20Snippets" @]
 [@ -> C:/Tcl_Applis/prog.tcl" @]

Btw, if using the user code from http://wiki.tcl.tk/9496, also add: "" { set prg "C:/windows/explorer.exe"} so you can also open folders! Hey this is from

Files, web pages, and applications can be launched much more easily in Windows with the ''start.exe'' command.  See my example of ''proc start'' in http://tcl.projectforum.com/notebook/52.
