Thank you for the response. I did a quick look over that message in the Microsoft forums, but it seems like you're talking about getting the character strings typed by a composed character. In my case, Code Writer *does* work to enter my composed characters from AltGr+<key> when I type them. However, if the AltGr+<key> sequence happens to also correspond to an Alt+<key> shortcut sequence, then not only does it insert the composed character, but it also activates the keyboard shortcut. It is this last part that I would like to avoid. I'm not sure how Windows handles these things.
In particular, I know that on other Operating Systems some applications incorrectly recognize raw Alt keycodes when recognizing shortcuts, rather than checking whether those Alt keys actually map to the "Alt" symbol in the keymapping or if the key has been remapped to another meaning, such as Ctrl or Compose. It seems that Code Writer at the moment does not distinguish from Alt and AltGr keys when using a keyboard created with MKLC that uses an AltGr key (that is, remapping the Right-Alt to an AltGr).
Are you saying that Code Writer cannot distinguish the difference, between, say, Alt+Shift+T and AltGr+Shift+T? This seems like something different than recognizing the strings received by the AltGr+Shift+T sequence itself. Code Writer does already successfully allow me to enter special characters, so I'm okay on that front. However, most of the applications I use are able to tell the difference between AltGr and Alt sequences, but it seems that Code Writer is not able to do so.
