Thanks for helping out.
Yep, the list is a bit buggy cos I've now noticed that LT will pick up on
Let's take the elevator (and tell me that 'elevator' is US English)
but no message comes up when I type
Let's take a/the/two can(s) of tomatoes (it doesn't tell me that 'can' is US English
I tried solving the space problem by adding a regular expression [\s] for 'space' between the two words but that didn't work.
But I'm very grateful for LT as it is freeware.
It's just that LT is there to eliminate mistakes so to have confidence in it, the lists should technically work 100%, otherwise it is misleading (you add expressions and think you are on safe ground)
