For what it's worth, this post contains an error in the line "xbindkeys --defaults > /home/edent/.xbindkeysrc" ... It would be better if the line was: "xbindkeys ––defaults > ~/.xbindkeysrc"

Also -- using the defaults per that line did some annoying stuff. Ctrl-shift-q will then bring up a window listing your xbindkeys configurations -- which is fine i guess, except more odiously, Ctrl-F (normally used for "find"ing things on a page) will be overwritten with a useless shortcut to xterm.

Simply comment those lines out of your ~/.xbindkeysrc file if you don't want those things, kill your current xbindkeys process and re-open it.
