Adding highlights:
Adding structure to your text:
All other lines starting with white space are shown as is.
Note: there's no way YET to undo or go back in history once changes are saved
To get more than one highlight on a single line, you can use returns to break the line in separate physicial lines. WiKit will concatenate them all into one. So if you do this (without indents):
I'm going to ''draw'' your ''attention''.
You'll end up with: I'm going to draw your attention.
It usually works (for non-pathological cases) just fine if you put everything on a single line. Experiment on the Graffiti page if you want to check whether anything in particular will work.
Using brackets in your text can be done by doubling them, so [[ shows as [.
