......you can customize your menus and add entries for applications that don't automatically appear after they are installed. To add, remove, or modify an entry, refer to the following procedure.

‪1.‬ Open KDE Menu Editor by right clicking on KMenu and choosing Menu Editor. If you have locked your Kicker, you can also open KDE Menu Editor by pressing Alt+F2 and typing kmenuedit followed by pressing the OK button.
‪
2.‬ In KDE Menu Editor's left-hand pane, choose the submenu the new entry should appear in.
‪
3.‬Choose File → New Item or press the New Item button. In the New Item window, choose a Name. Then add the Description, Comment, and Command. Select the icon by clicking on Icon. The Command will usually be the package name, Name is what will appear on the menu, and the Comment will appear in the tooltip that appears near the menu entry. Icons are chosen from /usr/share/icons/icon_theme directory by default, or can be chosen from anywhere in your files.

To change the order of menu entries, click and drag the entry in the KDE Menu Editor window.
