A few months ago, I submitted a patch that allows mouse click emulation using the keyboard to the Sourceforge patch tracker: https://sourceforge.net/p/dosbox/patches/264/

I haven't heard any comments about it. I don't really mind; I'm happily running my patched version locally, and I'm sure the developers are busy; I just wanted to ask if that's the right place to send patches, or if there's another place that's used for patches nowadays.
