[patch] this is in plaintext, the other one was gzipped

gpm-1.20.1balrog.patch (text/plain), 2.18 KB, created by Andrzej Zaborowski on 2005-08-07 07:57:32 UTC

Makes moving the mouse wheel in console equivalent to pressing the
arrow keys on your keyboard. It is done by writing the arrow key
codes to the terminal (Linux or VT compatible) whenever gpm detects
the wheels have spinned, similarly to how it pastes text on
pressing button 2.
