How to use the various features of the Able Editor.

# Options sidebar

Most options can generally be found in the options sidebar which can be opened by clicking the ••• button at the top right of the editor. This can also be opened using the shortcut Ctrl/⌘ + O.

This will allow you to edit your posts in more granular detail or paste pre-existing markdown into the editor. The editor will remember your preference, so if you prefer to use markdown mode it will stay in this state until you change back. # Math Equations You can write inline math equations or math equation blocks in your posts. We use KaTeX to render them. To write an inline equation just enclose your text within single dollar signs followed by a space. So typing something like -b \pm \sqrt{b^2 - 4ac} \over 2a into the editor followed by a space will render an inline equation. For block equations, just enclose your text in double dollar signs, so typing $$-b \pm \sqrt{b^2 - 4ac} \over 2a$\$ will give you a block-width equation like the one below.

$-b \pm \sqrt{b^2 - 4ac} \over 2a$
