Two mods (Auto Research and Foreman) used the same keybinding (Control+T). Clicking the keybinding caused one of the mod (Auto Research) to be triggered twice, the other mod not at all.
Suggestions:
Trigger both mods in case of duplicate keybinds.
Warn user on new/resumed game about any duplicated keybindings.
How they're handled is determined by how they register the hotkeys. If they register with consuming all or script then the other mod doesn't get the event.
Also I just tested with both of the mods you mentioned and when I set the hotkeys to the same value both events are fired in both mods:
