Select (V) · Drag a node or handle. Click an edge to select its contour. Shift-click or drag a box for multiple points: a box takes the nodes and handles inside it, Option / Alt only the nodes. Delete or Backspace removes them; a curve left behind keeps its shape as closely as one curve can, so extra nodes clean up easily.
Rounder and Squarer · Select the nodes or handles of curves, then click to shorten or lengthen their handles toward the corner where they meet. Each click changes the tension by the amount between the two buttons, 1 to 50%, 5% to start; type it or use its arrows. The readout shows the curve tension: about 55% is round, 100% square.
Curvature (C) · Shows a comb on every curve: the longer its teeth, the tighter the curve. Where the comb runs on without a step through a smooth node, the curvature is continuous. A step is a curvature jump, and its node gets a quiet ring; an orange ring is a kink where the outline should run smooth. Select one node to read its join below.
Pen (P) · Click an edge to split it. Click or drag in empty space to draw corner or smooth nodes. Click the first node or press Enter to close. Escape cancels.
Shift constrains node drags to an axis and handle angles to 45°. Option / Alt moves a node along its tangent with its handles fixed, or changes a handle’s length on its ray. Option + Shift slides a node along the curve. Add ⌘ / Ctrl to Option for a free, independent move. Option-click an edge to switch line / curve.
With one point selected, Tab cycles through points and Escape clears the selection. Arrows move 1 font unit, Shift + arrows move 10, and ⌘ / Ctrl + arrows move 100. Hold ⌘ / Ctrl for temporary selection. Space previews the fill and lets you pan.
Select two or more points to frame them. Drag an edge to stretch or just outside a corner to resize. Shift keeps the proportions. Drag the circle above the frame or just outside a corner to rotate. Shift snaps rotation to 15°. Drag the center cross to move the pivot. Option scales about the pivot.
Part grips · The orange diamonds hold parts of the letter: a serif, its bracket, the underside of a foot, a head, a bowl, an ending. Drag one to reshape that part wherever Apply changes to reaches, the whole typeface or the selected glyphs, like its slider. One drag is one undo step.
Choose a style under Across the family to see the glyph at that weight. Editing points there pins the whole glyph at that weight; a dot marks the styles drawn this way. Pin current keeps the shape as drawn. The weights between pins interpolate.
Pinch to zoom at the pointer. The Zoom slider and + / − zoom around the selected points. Scroll with two fingers to pan. Press 0 to fit the glyph. ⌘ / Ctrl + Z undoes one drag. Inserted nodes follow the same contour across family weights. Moving points or handles scales the correction to the local stroke thickness in each weight.
