Numeric Input

   Numeric input displayed in the 3D View footer.

Using the mouse for transformations is convenient,
but if you require more precise control, you can also enter numeric values.
After pressing the shortcut type a number to indicate the magnitude of the transformation.
Then confirm or cancel. e.g. pressing :kbd:`S 2`, :kbd:`Return` will double the scale of an object.

Translate :kbd:`G`
   By default and with no other key presses, the translation will occur along the X axis.
Rotation :kbd:`R`
   The rotation is in clockwise direction for positive values.
Scale :kbd:`S`
   Scaling works in almost identical fashion to translation.
   The primary difference is that by default, scaling applies equally to all three axes.

You can see the numbers you enter in the 3D View's footer.

.. tip::

   Numeric input can also be inputed in
   the :doc:`Properties </editors/3dview/object/properties/transforms>` region.


Simple Mode
===========

Blender has two "modes" a simple and an advanced one.
Simple mode only accepts simple numbers.
You can use basic :ref:`text editing <ui-text-editing>` except selection.

Decimals :kbd:`Period`
   Decimals can be entered by pressing :kbd:`Period`.
Negate :kbd:`Minus`
   Negate the whole value by pressing :kbd:`Minus`.
Inverse :kbd:`Slash`
   Hitting :kbd:`Slash` during number entry switches the number being entered to its reciprocal,
   e.g. ``2 /`` results in 0.5 (1/2); ``20 /`` results in 0.05 (1/20).
Reset :kbd:`Backspace`
   Hitting :kbd:`Backspace` after having deleted all leading chars will first reset
   the edited value to initial state, and on second press, the whole number editing will be canceled,
   going back to usual transform with mouse.
Next/previous Component :kbd:`Tab`, :kbd:`Ctrl-Tab`
   To enter numeric values for multiple axes, use :kbd:`Tab` or :kbd:`Ctrl-Tab`.
   e.g. To move an object, one Blender unit on all three axes press:
   :kbd:`G 1` and :kbd:`Tab 1` and :kbd:`Tab 1`.

Non-number Inputs
   You can also combine numeric input with
   :doc:`Axis Locking </editors/3dview/object/editing/transform/control/precision/axis_locking>`
   to limit movement to a particular axis or tool specific shortcuts.


Advanced Mode
=============

In advanced mode you can additionally enter expressions and units.

Use :kbd:`=` or :kbd:`NumpadAsterix` to enable advanced mode, and
:kbd:`Ctrl-=` or :kbd:`Ctrl-NumpadAsterix` to switch back to simple mode.

It features:

- Units (cm, ", deg, etc.).
- Basic operations from python/BKE_unit (``+``, ``*``, ``**``, etc.), and
  math constants and functions (pi, sin, etc.).

You can still use the negate and inverse shortcuts (:kbd:`Minus`, :kbd:`/`), as well as non-number inputs,
but you have to hold :kbd:`Ctrl` to activate them.
