[Pythoncard-users] menu accelerator conventions, plus vs minus

I'm using wxPython 2.3.2 and menu accelerators such as Ctrl+C are working
(they were broken in 2.3.1). Apparently you can use either '-' or '+' for
the key descriptions:
  Shift+Ctrl+O
  Ctrl-Shift-V
  Ctrl-X
  Alt-X

I've been using '-' since that is what I copied out of the very first
wxPython app I borrowed from when we started PythonCard. When I look at
other apps under Windows, '+' seems to be the standard.

So, I'm wondering what is common for Linux, plus or minus? Also, this seems
like another place where the Mac might need a separate resource, since the
Mac would use Command-C or Apple symbol-C (if I remember correctly).

I'll probably do a global replace from the minus to plus form for the menu
accelerators unless Linux uses the minus form, in which case a better
solution may need to be used. Theoretically, the framework could
"auto-correct" the accelerator form based on platform when the resource is
read in.
