Why we like it

Stands out in the blender_extensions library for keeping numeric entry under the cursor, with a calculator that handles unit math and angle conversion inline.

What is On-Screen Numpad?

On-Screen Numpad brings a numeric input dialog to Blender that opens right where the cursor sits. Press the hotkey while hovering over a numeric property field and a calculator-enabled dialog appears, letting you type values without moving the mouse away. It works with almost all numeric properties in Blender, including Transform values, node settings, and light and camera settings.

The dialog handles arithmetic, power operations, and calculations with parentheses, plus math functions such as sin, cos, tan, sqrt, log, and abs, and constants like pi, e, and tau. So 50*2.54 returns 127 and sqrt(2) returns 1.414. With Auto Angle Conversion enabled, numeric inputs are treated as degrees and converted to radians, and explicit conversion functions are available for precise control.

Settings cover a phone-style keypad layout, property path display, function buttons, calculation history, dialog width, and decimal places. You can choose to use the current value as the starting point and apply property limits automatically. The default hotkey is Ctrl + Right Click and can be customized.

Who is On-Screen Numpad best for?

On-Screen Numpad is best for blender users who enter numeric values frequently and want calculator input without moving the mouse away from the property field.

How much does On-Screen Numpad cost?

On-Screen Numpad is completely free to download and use.

How do I trigger the On-Screen Numpad dialog?

On-Screen Numpad opens its dialog when you press a hotkey while the mouse cursor is over a numeric property field. The default hotkey is Ctrl + Right Click, and it can be customized in the settings. The dialog works with almost all numeric properties in Blender, including Transform values, node settings, and light and camera settings, so you can enter values without moving the cursor away from the field you are editing.

What calculations can On-Screen Numpad handle?

On-Screen Numpad supports arithmetic, power operations, and calculations with parentheses, along with math functions such as sin, cos, tan, sqrt, log, and abs, and constants including pi, e, and tau. For example, 50*2.54 returns 127 and 2*pi*5 returns 31.416. When Auto Angle Conversion is enabled, numeric inputs are treated as degrees and converted to radians, and explicit conversion functions are available when you need precise control over the result.
