This category is where labels can be modified. In general, each sub-category corresponds to the main areas available from the Desktop (Funds Management or online sales), and then is broken down into the main pages within those applications (Campaign or shopping cart).
When working with this category and sub-categories, the Key column contains the name of a field, tab, button, title, pop-up message or other variable (createNewButton) and the Label column contains the text that is displayed to the user (Create New), which you can modify.
