OK, this will seem strange, but it's very difficult to get old programmer's like me to change. I've used an editor for the past 1,000 years that use ALT-S to bring up a search dialog. Each editor I use, (DEVC++, MultiEdit, etc) I've been able to configure the hotkey.
Not Code::Blocks. I can't find a way to make the change.
Is it possible somewhere - some hidden XML? Or is this a hard coded setting?
