Ah, even tap and hold would work when keyboard cannot be used.
I personaly prefer this way. In case you guys are still looking for this, there is Mousetweaks, from the gnome project. Don't worry, it won't hurt to install. Just some minor gnome libraries.It can be downloaded
here. For debian, you can get the mousetweaks and at-spi packages. To make it work, just run:
/usr/lib/at-spi/at-spi-registryd
mousetweaks -e delay
You can make it run with your favorite session manager by adding these two to the init scripts.
The debian packages can be easily (?) ported to angstrom and pdaxrom.
