That doesn't work on my end.

The Escape key will bring up new actions or if I tap near the top of the screen, but a long hold does nothing.

Even still, certain games (Broken Sword, Discworld, etc.) require a right click so this is what I have:

/home/user/.xbindkeysrc_scumm
"xmodmap -e "pointer = 3 2 1""
Right

"xmodmap -e "pointer = 1 2 3""
Left

I launch this before SCUMM fires up:
xbindkeys -f /home/user/.xbindkeysrc_scumm

If someone would like me to newbie package that together, just ask.

It also works with Dosbox for games like X-Com but I would remap the hardware keys differently.

SCUMM doesn't really have any need for the D-Pad but Dosbox usually does.

It still would be nice if I only had one key for this... Hold a hardware key and tap for a right click, but I don't know how to term that in the config file.

Oh, and how did this thread get derailed from only talking about me and my needs?

I'm also waiting to hear back from the author of Vagalume on pumping out the volume even louder. I'll email him again later tonight.

God bless.
