Installed from:    Ubuntu Packages

Many actions in KDE are difficult to perform without a mouse. For instance, in Kontact one can easily switch to the application that he wants (say, Contacts) with CTRL-#. But once there, the only way to switch between fields without the mouse is with the Tab key. This is difficult, as it is not always obvious nor intuitive to which field the focus will jump next, and some fields do not give any indication at all that they are focused (such as the list view window).

Therefore, I propose a solution that I saw recently in Microsoft Office 2007. When one depresses the Alt key, all menu items and "clickable things" get a letter marked next to them. Clicking the letter performs the action, or gives more choices if appropriate (such as in menus). This makes navigating the app much easier for those of us who cannot operate a mouse.

Note that there is precedent for this type of functionality already in KDE, in Konqueror. When browsing webpages, pressing CTRL brings up exactly the type of functionality that I describe, for browsing webpages. So there is no worry of MS suing: quite the opposite, they seem to have stolen the idea from KDE. Does that mean that they have to GPL Office? :)
