Package: xbase-clients Version: 4.3.0.dfsg.1-10 Severity: wishlist File: /usr/X11R6/bin/xmessage Without a mouse, the user is unable to click the 'okay' button of $ xmessage hi Therefore perhaps TAB RET should do the job. Also TAB should jump amongst buttons if more than one. P.S. perhaps fix $ xmessage --help to at least print an error, if not help.
