Pressing alt in research menu.

When you go inside of the technology/research menu, and press alt while inside, it plays the sound to trigger alt mode. This does not actually change it inside of the menu nor outside when you leave it. Instead, it would make sense to play no sound since you are not allowed to change alt mode inside of that menu, or have it change the alt mode while inside like normal.

Thanks for the report however I don't believe we will be doing anything about this. Most sounds in reaction to key presses are best-guess that the action will happen but are not guaranteed. In this case the technology GUI being open in single player means the game can be paused (but is not strictly required to be). The logic plays the sound regardless.

Alright.
