A minor point: on the page ‘Operators’ in the latest beta (3.0pb3) help file, it says:
Note: The symbols above are also used by the Finder and Spotlight for searches. Enter the vertical ruler character for the OR operator by pressing Shift-7.
This is wrong for UK Mac keyboards, at least, where shift-7 is ampersand ‘&’. Shift-\ gives the pipe ‘|’. Might be worth adding an ‘other keyboard layouts are available’ rider?
Regards and thanks for a fine program.
