Why do the equations seem to run off the page for me? And I can’t follow by swipping… ---

> [@Joey\_P](#): > > must the context menu that pops up when you right click on the equation be glowing like that? You must be using a dark theme. With a light theme, there’s just a drop shadow. The shadow looks fine, but in dark mode it’s reversed, giving it a glow instead of a shadow. I agree that it looks a bit odd. ---

> [@mikecurtis](#): > > Why do the equations seem to run off the page for me? The formatting for long expressions isn’t great, particularly on mobile (probably Discourse’s fault). However, you can see the whole expression by right-clicking (or long-pressing) to bring up the context menu, then going Math Settings-\>Zoom Trigger-\>Double click (the others don’t work on mobile). Then double-tap the expression and it will bring up a zoomed, scrollable pop-up window. ---

> [@glowacks](#): > > edit: That’s a negative. Quoting it just doesn’t work. Highlight quoting never captures formatting correctly. I recommend only using it on plain text (Italics, bold, and links are fine.) Instead, you can click reply and then click the quote icon in the upper left, then edit out any part you don’t want to quote. ---

I think I get it now. Still pretty labor-intensive. Getting a colors icon in the edit box would be nice (although I suspect that keeping it labor-intensive might be the preference of TPTB).
