coming from unix it's a pain in the butt to click
your way trough windows fileDialog to check one
MEL-file in your favorite textEditor.
this is the shortcut from maya directly to your textEditor.
Works for TEXTPAD and NOTEPAD and SCRIPTEDITOR so far,
but if you know MEL a little it can easily be expanded
to work with other Editors.
NOTEPAD and SCRIPTEDITOR are only experimental entries
to show what can be done. In scriptEditor-mode it
works the same as "scriptEditor|File|Open Script":
it prints the script into the 'input'section and
erases anything there prior. so beware! ...and Enjoy!
p.s.: check the script and edit file location of textpad to suit your needs
