You can type function names using your keyboard:
Example: Type sin(30) directly
Type constant names directly:
pi or PI - Pi (π)e or E - Euler's numberStandard copy/paste operations are supported:
Ctrl+C / Cmd+C - Copy selectedCtrl+V / Cmd+V - PasteCtrl+A / Cmd+A - Select allCtrl+X / Cmd+X - CutCopy expressions from other sources and paste them into the calculator
