Hi, guys.
I wanted to set the Go->Back command to Backspace.
I found the VK_BACK_SPACE definition in dom_events.xpt,
but it's not in in gkcontent.dll

you're looking in the wrong place, look here:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/kmeleon/k-meleon/AccelParser.cpp?rev=1.15&content-type=text/vnd.viewcvs-markup
or here:

Thank you, Brian.
Could you be more specific, what VK_ constant to use in the Accelerator Definition File for K-Meleon to set the "Go-Back" command to Backspace.
I tried VK_CLEAR and a bunch of others, but they all don't work.
Thank you again.

Disregard the above, I think I found the solution.

I'm sorry, I didn't.

Finally! It's "VK_BACK".
