Images
,image
drop an image file onto a pane and it lands where the dashed placeholder shows, or paste one straight into a line
drag a corner handle to resize; click the picture to see it full size and Escape to come back
the marker on its own gives you an empty picture slot to fill later
Formulas
,latex
hands you an empty formula; put the source inside the marker and KaTeX renders it
eiπ+1=0\displaystyle e^{i\pi} + 1 = 0
the pencil turns a formula back into its source, and the tick turns it back into a formula
backslashes survive being typed, so a command like \frac needs no doubling
Quotations
,cite
sets the text as a block quotation — no highlighting and no language, just the words
A name is one element across the whole space. Write it twice and the two places have already found each other.
