It seems btnx is unmaintained and on its last legs (see Comment 30 in Gentoo Bugzilla Bug Report No. 188265
). Even the Web site of its author is up for sale.
However, perhaps Easystroke
or and/or AutoKey
might be of some use to you. I have both installed and use them both regularly.
I can configure Easystroke
to do certain things when I move my mouse etc. For example, I can click my mouse's scroll-wheel and draw a 'd' with my mouse on my screen to launch Dolphin, or click my mouse's scroll-wheel and drag the pointer diagonally downwards from left to right to add "---------- Original Message ----------" in an e-mail Compose window, and so on. I can configure AutoKey
to do certain things when I press certain keys. For example, when I type "esigw" at the end of an e-mail it is replaced by my work signature, when I type "esigp" at the end of an e-mail it is replaced by my personal signature, and when I press Ctrl-Alt-d the date command is executed and the date and time are typed for me. AutoKey can be configured to run all sorts of scripts.
I have easystroke-0.5.5.1 and autokey-gtk-0.81.4 (the latest versions of both) installed on my machine from a Portage local overlay. If you don't know how to use Portage, I suggest you file a bug report (see link 'Bugs' at the top right of this page) and request the Entropy repository maintainers to build them and add the binary packages to the Entropy repository.
