Simon, I assume you're using a touchpad and sometimes knock your palm against the touchpad while you're typing?
There are a number of solutions to this. I can't tell you the best one without knowing your exact setup. But, almost all of them wouldn't involve actually configuring awesome, they would involve other programs. I guess, you could probably use Awesome to do this, but I would not. Any solution would likely be quite fragile and complex enough that it would be annoying to write and even worse to attempt to configure. But, if you figure out what driver you're using, it wouldn't be that hard to enable one of the many solutions. The Archwiki gives a number of potential solutions to this problem if you're using a synaptics touchpad with the synaptics driver: https://wiki.archlinux.org/index.php/Touchpad_Synaptics#Disable_trackpad_while_typing. Depending on your distro, there may be some packaged tools that would aid in this (I know ubuntu comes with tools to disable the touchpad while typing). Generally, I think you'll have a much easier time locking it with other tools than with awesome itself. -Greg
