Keyboard Shortcuts
The calculator is built around a real text field, so ordinary typing and editing work exactly as you would expect - plus a few substitutions.

Entry and evaluation
| Key | Action |
|---|---|
| 0–9 and . | Enter digits and the decimal point |
| + and − | Add and subtract |
| * | Inserts × (multiply) |
| / | Inserts ÷ (divide) |
| ^ | Power |
| ( and ) | Parentheses |
| Enter | Evaluate |
| = | Evaluate |
| Escape | Clear everything, or exit full screen |
| , (comma) | Argument separator, inserted with a trailing space |
Editing
The expression area is a standard text field, so every editing key your browser and operating system provide works without the calculator intercepting it:
| Key | Action |
|---|---|
| Backspace | Delete the character before the cursor |
| Delete | Delete the character after the cursor |
| ← and → | Move the cursor |
| Home / End | Jump to the start or end |
| Shift + arrows | Select text |
| Ctrl / ⌘ + A | Select the whole expression |
| Ctrl / ⌘ + C, X, V | Copy, cut and paste |
| Ctrl / ⌘ + Z | Undo |
| Ctrl / ⌘ + Y or Shift + Z | Redo |
This is a deliberate design decision. Calculators that reimplement their own text field usually get undo wrong, or break the clipboard, or fight the operating system's selection behaviour. Leaving the field as a real text input means all of that works for free, and works the way your muscle memory already expects.
Tips
- Operator keys insert a trailing space, giving long expressions a clean place to wrap rather than breaking a number in half.
- Paste an expression from anywhere - it is parsed the same as typed input. If it fails, see error messages.
- The history panel keeps previous calculations; click one to load its expression back into the editor.
- Escape clears the expression, but exits full screen first if you are in it - so it takes two presses to clear from full screen.
Frequently Asked Questions
Can I use my keyboard with this calculator?
Yes, fully. Digits, operators, brackets and Enter all work, and the expression area is a real text field so editing, selection and the clipboard behave normally.
How do I multiply and divide from the keyboard?
Press * and /. They are displayed as × and ÷ in the expression.
Does undo work?
Yes. Ctrl+Z (⌘+Z on a Mac) undoes, and Ctrl+Y or Shift+Ctrl+Z redoes. The calculator passes all Ctrl/⌘ combinations through to the browser rather than intercepting them.
What does the Escape key do?
It clears the expression. If you are in full screen, the first press exits full screen instead.
Can I paste an expression in?
Yes, with Ctrl+V or the Paste chip above the keypad. Pasted text is parsed exactly like typed input.
