Several ways to work with value fields

Usually you type a number into int or float fields to change a value. Maya's user interface provides additional functions to alter a value.

• First of all you can use a virtual slider in every user interface window except the Channel Box. To activate it just hold CTRL and drag with the left, middle or right mouse button over the UI field to change the value. The left mouse button will add or substract in 0.01 steps, middle mouse button in 0.1 steps and right mouse button in 1.0 steps.
• In most windows you can also use simple expressions to alter values. To change selected keys in the graph editor just type +=, -=, *= or /= to add, substract, multiply or divide based on the current value. Multiply selected components are handled properly.
  
  +=3 will add 3 to all current values.
  
• To enter simple expressions in the Attribute Editor simply type "=" followed by the expression you would like to set up.
  
  =frame/2 will create an expression that sets the value in the field to frame / 2.
