KScannerButtons is a daemon plus an optional KDE frontend for monitoring your scanner buttons so that actions can be taken in response to button presses. It's composed of a daemon (sanebuttond), a frontend that will display an icon in the systray, and a dialog box to configure and launch the daemon. It is based on the button monitoring capabilities found in some SANE backends. It has been tested with the avision backend and an HP 5300C scanner. The frontend requires Kommander (kde-webdev).
