Lubuntu uses Openbox as its window manager. ~/.config/openbox/lubuntu-rc.xml is a file that specifies, among other things, keybinds for various commands.

Most of the keybinds in lubuntu-rc.xml use modifier keys such as Control, Shift, Alt, and Super.

For example, one way of opening a terminal window would be by pressing Control+Alt+T together:

<!-- Launch a terminal on Ctrl + Alt + T-->
<keybind key="C-A-T">
  <action name="Execute">
    <command>lxsession-default terminal</command>
  </action>
</keybind>

But there is also this:

<!-- Keybinding for terminal button-->
<keybind key="XF86WWW">
  <action name="Execute">
    <command>lxsession-default terminal</command>
  </action>
</keybind>
<keybind key="XF86Terminal">
  <action name="Execute">
    <command>lxsession-default terminal</command>
  </action>
</keybind>

What are keybind key="XF86WWW" and keybind key="XF86Terminal"? How do I locate these keys on my laptop's keyboard? My laptop is a Dell Inspiron N 1545 from 2008.
