I think the command you are looking for is:
iwlist wlan0 scan
Which will show a list of available Wi-Fi networks.
If you are connected to a network already you can see a list of the other devices on the network with:
nmap
To launch the terminal using a keyboard you can create a keyboard shortcut such as Ctrl+Alt+t. To do this first run:
nano ~/.config/openbox/lxde-rc.xml
This will allow you to modify the ~/.config/openbox/lxde-rc.xml
file.
Anywhere between the <keyboard>
and </keyboard>
tags add:
<!-- Launch terminal when ctr-alt-t is pressed -->
<keybind key="C-A-t">
<action name="Execute"><command>lxterminal</command></action>
</keybind>
If you put this piece of code just before the </keyboard>
tag it should look something like this:
<!-- Launch gnome-screenshot when Print is pressed -->
<keybind key="Print">
<action name="Execute"><command>gnome-screenshot</command></action>
</keybind>
<!-- Launch terminal when ctr-alt-t is pressed -->
<keybind key="C-A-t">
<action name="Execute"><command>lxterminal</command></action>
</keybind>
</keyboard>
