Within the Drupal menu system descriptions can be added to menu items. These descriptions are often presented as tooltip text through setting the title attribute of the menu item anchor to the value of the menu item description. One example of this can be seen in (Issue #510094) Add description to the link items of the toolbar.
I do not believe that the menu item description necessarily is important, or that it always improves usability. However, in some situations, like an administrative toolbar, I believe that the description of the role of each toolbar menu item is important, especially to new users. I am wondering if anyone has ideas that would supplement the use of the title attribute to ensure that as many users as possible have access to the menu item descriptions for toolbar menu items.
My initial thought is to use technique C7: Using CSS to hide a portion of the link text in combination with the title attribute for menu items where the menu item description contains important information. However, this still means that non-screen-reader users who cannot access or perceive the tooltip text do not have access to the menu item description.
