I'm currently using an English keyboard with an "International" configuration to write in spanish. I use the shortcut AltGr+A to write "á", AltGr+E for "é", and so on for each vowel.
In TeXstudio I have no problem with á,é,í or ó, but when I try to write the "ú" character I get a small window with characters, instead.
I've searched in the shortcuts options, looking for some action related to AltGr+U (or Ctrl+Alt+U, which is the same) but I found none.
Is there a way to disable that specific shortcut?
