A family of Microsoft word processing software products for creating web, email, and print documents.
Rats! The keystrokes just got reassigned. So turning off Dictation does not alter all this! (Yes, I had turned on Dictation at one point, speaking rather than typing in a series of numbers).
At least, quitting and restarting Word still works.
And, reassignment is much easier to live with than the crashes on command-f! (Which can lose one unsaved work!)
H'm… I may set up a macro that automatically saves before starting a search (hence, command-f would issue a command-s followed by Advanced Find & Replace).
I even tried creating a main-level menu item under Edit for the Advanced Find. No dice! I wonder what's different about your set up that command-F (for AFR) works OK?!
