# Math Virtual Keyboard
Typing math requires access to many special symbols. While [keyboard
shortcuts and inline shortcuts](/mathfield/guides/shortcuts) can help when a
physical keyboard is available, touch-enabled devices without a physical
keyboard attached need another solution.
The **math virtual keyboard** is a keyboard displayed on screen that gives
access to specialized symbols for math input with only a tap.
### Layout Selector
The math keyboard includes multiple **layouts** which can be chosen with the
layout selector.
The default layouts include the most common math symbols. They are:
**numeric**, **symbols**, **alphabetic** and **greek letters**.
These layouts can be customized to fit specific needs. Learn more about **customizing virtual keyboards**.
### Undo/Redo/Paste
The **Editing Toolbar** display icons for common editing functions: **Undo**,
**Redo**, **Paste**, **Cut** and **Copy**.
If you have a physical keyboard attached, these commands can be invoked
with their corresponding keybindings: Ctrl/Command+Z,
Ctrl/Command+Y, Ctrl/Command+V,
Ctrl/Command+X and Ctrl/Command+C.
### Shift Key
Press the **Shift Key** ⇧ to access alternative symbols. The
keyboard updates when the key is pressed to reveal the symbols.
If a physical keyboard is available, the SHIFT or
CAPSLOCK key on the physical keyboard can also be used.
The symbol corresponding to the shifted variant is displayed
in the top right corner of some keys. Some keys have a shifted variant even
though they may not include a top-right label.
### Variants
A key **variant** is a symbol that can be accessed by a **long press** on a keycap.
The variant is often related to the original symbol.
**To display variants related to a keycap**, press and hold the keycap.
Many keycaps have variants, but a few don't.
