// A `dijit.form.NumberTextBox` extension to provide keyboard accessible value selection

|
|
// as well as icons for spinning direction. When using the keyboard, the typematic rules

// apply, meaning holding the key will gradually increarease or decrease the value and
|
||
|
|
// accelerate.

|
||
|
|
// | new dijit.form.NumberSpinner({ constraints:{ max:300, min:100 }}, "someInput");
