Ok, i have configured doom with dosbox and i modified it with the novert.com so that i can use the mouse to turn and not use the vertical axis (move forward/back)

I modified the default.cfg file so i have always run on.
There is just one problem, i am used to using the right mouse button to open doors and in a way it works, double right clicking opens doors but its just a pain to do.

Is there a way to modify the default.cfg so that i can map the right mouse button to just open doors with a single click ?
I would like to avoid extra programs like hotkey programs. Anything that works inside dosbox (like the novert.com) should be ok.

Also is there a way to bind previous and next weapon ? Doom didn't have a previous and next key in the setup. it seems you can only use the number keys to switch your weapon.

It's crazy how much better Doom plays in dosbox compared to Gzdoom or other ports. But i do use Gzdoom for certain specialised wads and mods.
