I found a small anomaly in the lua editor...
Type this and keep a close eye on the 1st line you type, as you type (ie: don't copy/paste)
There's actually a lot of variations you can do to make it happenCode:-- this_is_a_test -- this -
Cope/paste this:
Now put your cursor after "test" on the 1st lineCode:-- this_is_a_test -- this_is_a_test -- this_is_a_test
now put it on after "test" on the 2nd line, then 3rd.
For me -- on two machines, the underscores above disappear.
