Changing the case of selected text

Perform the following steps to change the case of selected text in a document to lowercase, UPPERCASE, or Title Case:

  1. Select the desired text to change the case.

  2. Click on the Case Change icon in the toolbar.

  3. From the drop-down menu, choose the desired format by clicking on either lowercase, UPPERCASE, or Title Case.

The toolbar button will retain the last applied type of case making it simple to apply the same formatting multiple times.

Types of Formats

Currently, there are three types of formats available:


The lowercase option changes all the selected characters to lowercase. This is a handy option in situations when the Caps Lock key was accidentally left on while typing. Instead of starting over and retyping everything, the user can simply select this text and change words to lowercase if they have been erroneously capitalized in the input.


The UPPERCASE option changes all the selected characters to uppercase. This formatting option is useful in documentation, where "initial caps" are to be used ("headline style") as opposed to sentence style (first word of sentence or phrase capitalized only), regardless of the specific type of title, heading, header, or interface text.

Title Case

The Title Case option changes anything other than articles, coordinating conjunctions, or short prepositions to capital letters. The default rule set for Title Case is based on Wikipedia Title Case.

Title Case options

Title Case can be customized to create user defined rule sets by using the following options:


The casechange_title_case_minors option is used to customize the rules while using Title Case. This option makes it possible to configure what words not to capitalize. All other words not specified by this rule set will be capitalized overriding the default Title Case rule set.

Type: Array

Default: A rule set based on Wikipedia Title Case

Example: Using casechange_title_case_minors
  selector: 'textarea',  // change this value according to your HTML
