Keeping the competition in the text expansion world going, Ettore Software has now released TypeIt4Me 5.2, adding compatibility with Mac OS X Lion. Also new in version 5.2 are the capability to issue a Shift-Tab keystroke combination and a Date/Time Math function that can have a date abbreviation expand to a date or time in the future or past. ($19.99 new, free update for purchases since 1 January 2010, $8.99 upgrade otherwise, release notes)
I've been using this program for years and glad to see an upgrade - even though it will cost me $9 - my only quibble is the system for editing - just a bit clumsy. Downloaded the update - now to pay the bill.
