This patch includes an enhancement requested frequently on the mailing list.[1][2] It adds a variable, cur_phonetic in the spk_vars, which can be set as a module parameter, as well as in /sys/speakup/cur_phonetic. This patch also documents cur_phonetic as a sysfs attribute in sysfs-driver-speakup. When cur_phonetic=1, it causes speakup to speak letters phonetically if paused on the character while arrowing through a word. When a user does not set cur_phonetic to any value, the default value for it would be 0.
