   - Cmd/Ctrl+Alt+L (`ui.newLayer`) opens Layer Options for a new layer, as an Alt-click on the Layers panel's New Layer button does, on the key the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists for adding a layer through the New Layer dialog box. OK adds the layer above the current layer, and Cancel adds none. Cmd/Ctrl+L still adds a layer without the dialog.
   - F8 (`ui.symbolOptions`) opens Symbol Options for a new symbol made from the selection, as the Symbols panel's New Symbol button does, on the key the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists for making a new symbol. OK makes the symbol and puts an instance of it in place of the art, and Cancel makes none. With nothing selected, F8 opens no dialog, and the status bar says that nothing is selected. Shift+F8 and Cmd/Ctrl+F8 still show the Transform and Info panels.
   - Cmd/Ctrl+Shift+X (`type.resetHorizontalScale`) sets the horizontal scale of the selected type, or of the text the Type tool has selected, to 100% as the Character panel shows it (the object's own stretch included), in one undo step; at a caret it leaves the text as it is.
+  - Cmd/Ctrl+Shift+U (`type.underline`) underlines the selected type, or the text the Type tool has selected, and removes the underline again, as the Character panel's Underline button does. Cmd/Ctrl+Alt+Shift+C (`type.lineComposer`) switches the paragraphs between the Single-line and the Every-line Composer, and Cmd/Ctrl+Alt+Shift+H (`type.hyphenate`) turns their hyphenation on and off, as the Hyphenate checkbox does. These are the keys the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists for underlining and for toggling auto-hyphenation, and on Windows for toggling the line composer. The page's macOS key for the line composer ends after Command, and VectorCraft uses C there as well.
   - Cmd/Ctrl+Alt+N (`file.newWithoutDialog`) makes a document without opening the New Document dialog, on the key the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists for making a new document with no New Document dialog box. The page does not say which settings the document gets. VectorCraft gives it the settings the dialog opens on (the first Recent entry, or the Print category's Letter while Recent is empty) and the next untitled name.
   - Cmd/Ctrl+F6 (`window.nextDocument`) and Cmd/Ctrl+Shift+F6 (`window.previousDocument`) make the next and the previous open document the current one, in tab order and as a click on its tab does, on the keys the reference app's [Default keyboard shortcuts](https://web.archive.org/web/20260726060015/https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html) page lists for navigating to the next and the previous document.

The page does not give an order. VectorCraft steps through the units in the order a right-click on a ruler lists them (Points, Picas, Inches, Millimeters, Centimeters, Pixels, Feet & Inches, Meters, Yards, Feet) and goes from Feet back to Points.
