RE: Locating Iup Key Codes in Lua: which Table's Fields Are They?

["Antonio Scuri" <scuri@...>]

  Call "iup.key_open()" in Lua. It will initialize the key names.

  This function is listed in the System/Reference tree of the manual, but it
is not linked to any article. Something is missing of course, it should be
linked in the Keyboard Codes page, sorry.

Best,
scuri
