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.
