Two days ago Ctrl-T stopped working. Using edit menu covered usage.
Reset preferences to no avail; even uninstalled WACOM tablet, no joy.
However, now using Ctrl-Alt-T (discovered by accident) performs the function. Editing keyboard shortcuts shows Ctrl-T as the proper setting and unable to locate the C-A-T setting to remove it, should it be the culprit.
This affects both my CS6 and CC (2021). Both were reset but problem remains.
