How do I fire mines?

Here’s one of those idiot questions, but I can’t find an answer.

If I’m in a larger ship that supports mines (or, at least, I assume it does, judging by the icons on the lft side)… then how do I fire them?

I checked under the keybinds, and there’s nothing there. Chaff is chaff. The missile-keybind doesn’t seem to work either (unless these ARE categorized under missiles, but “conditions” apply before a mine can be placed)…?

So… help, please?

Only the destroyer has mines at the moment. You can fire mines in the menue were the weapons are, or the other were the warp option is, not sure which atm.
