Type it, or click it together. The line above the input shows the regulated template of what you are composing — unfilled slots stay grey, named by what they are waiting for — and everything you build is read back to you in plain English, live. This is the fastest way to learn the Lingo.
Every button writes into the input above, exactly as if you had typed it. Short forms are shown in cyan — typing just the short form works too; that is the type-ahead rule.
One instruction. Both slots come from the registry — nothing custom appears in either.
Directives fused with slashes inside one token. They compose at once, across axes.
Directives side by side form one act — canonically a mem: operation taking a sibling as its object.
Compounds joined by &. Strictly in order — each completes before the next begins.
Brackets make directives one unit; inside, they refer to each other. A group can be a single object — mem:pin (gen:doc & gen:deck).
A parenthesised point, for style: and scale: only — absolute coordinates; any axis not named sits at 0.
