Ribbon tabs

The ribbon is the strip of tabs under the dark Quick Access bar. Click a tab to change the buttons underneath. Calculeaf remembers the last tab you used on each worksheet.

Quick Access

The dark bar above the tabs is always visible. From the left: the Calculeaf mark, then New, Save As, Export .leaf, Import, and Share. After a divider: Undo and Redo. The worksheet name sits in the middle — click it to rename the sheet. Sign in (or your initials) sits on the right.

These buttons repeat on the Home tab so you can reach them without leaving Math or Insert. Tooltips name the action if the icon is unfamiliar.

Home

• File — New, Save As, Export, Import (Calculeaf .leaf or Mathcad .mcdx / .xmcd).
• Calculate — the Evaluate button re-runs every region in visual order. Tooltip: Evaluate All. Shortcut: Ctrl+Enter (Command-Enter on a Mac).
• Edit — Cut, Copy, Paste, Undo, Redo for selected regions.
• Units — SI, USCS, or CGS for this worksheet.
