Not sure the tab key would work on the web app at all, but you can always indent with at least one space before the bullet (I usually put in two). E.g.
That will work for me. I wonder if that’s how I did it in the past…
(problem of using too many different online documented editors that all work differently…)
Just tried the two-space method and it did not work. What is your actual set of keystrokes between the first item and the next indented item?
Trying here:
List item
List item
List item
List item
Here I can move mu cursor the the beginning of the line to insert 2 spaces. In Wrtie.as, I was unable to move my cursor to the start of the line to insert spaces before the bullet.
