Change content of WordPress Editor Buttons

Not every user likes the default settings how some buttons are displayed on the WordPress editor. As of right now, there is no possibility to adjust it directly via a filter. The following source code describes a solution to change the link buttons and their content to easily set links with custom values. The small Plugin changes the values with the help of Javascript and returns a popup for set links with custom values inside the Plugin.

The following source change the strings and you see the result on the screenshot below.
