Multiple weapon slots

In the inventory there are two slots for weapons. Is there a way to switch between the two weapons without going to inventory screen ?

Thanks

Yes.

There is a hotkey. I don't know it but you can look it up in your options under keybinds.

Furthermore, in the gem menu you can set specific skills to only use a specific weapon slot if you so choose. If so, when you use this skill it will automatically switch to the selected slot. In order to switch back you would need to press the keybind or use another skill that only uses the other weapon slot.
