Hi,

I was wondering if it is possible to assign a key combination to a single key using DOSBox's keymapper. To be precise, I would like DOSBox to send a Ctrl+a event when I press the a key on my keyboard.

I have read the keymapper's documentation and tried to remap in a few ways without successfully acheiving the desired result. The reason I want this mapping is to strafe left and right in Wolfenstein 3D using just the a and d keys, without having to manually press the strafe toggle key.

One thing I tried was to just add key_a and key_d as new bindings to the left_ctrl_key event. I would have thought pressing a would then send both a left_ctrl_key and a key_a event. However this does not seem to do the trick in Wolf3d. Is there a way to send an actual Ctrl+a event?

I also tried using the mod1, 2, 3 and hold buttons in the keymapper interface, but I don't quite understand how those are supposed to work.

Thank you!
