[SA] tank not shooting

[J-H]

2.08. I have a tank equipped with red ammo in the submachine gun slot, no shells or flame ammo. Pressing C or spacebar won't make it shoot at biters. The "big gun" weapon is back-shaded in red, so I think it's trying to shoot that instead of a weapon that actually has ammo.

Pressing Q does not change weapons.

Anyone else having this error?

You have Q bound to Next weapon?

Yeah, according to my Controls settings. I don't recall changing any of my hotkeys in the last 7 years. What's the correct hotkey supposed to be for next weapon?

Upon further examination, it looks like Q is also clear cursor and a pipette tool.

Next Weapon was Tab in 1.1, and C in 2.0.

Thanks!
My keybindings probably date back to about 0.13.
