Create New Keyboard shortcuts

There is no automatic way to create new keyboard shortcuts or hotkeys in lubuntu. You will either have to edit Lubuntu's openbox configuration file (~/.config/openbox/lubuntu-rc.xml) and edit, or alternatively install xbindkeys.

Obkey will edit the keyboard parts of your Openbox configuration file for you. Download the .tar.gz and unarchive it. After unpacking the tar.gz, open a command line in the new folder and run obkey like this: ./obkey ~/.config/openbox/lubuntu-rc.xml
Hint: back up your config file.
After saving the config file, you will need to run this command to have openbox use the changed config: openbox --reconfigure

For more information on the syntax of the configuration file, please check out the official Openbox documentation on bindings. Note that Super_R and Super_L are the two "Windows" keys when you just want to use those keys. If you want to couple them with something else, use W- plus whatever key you want to use.

Multiple keyboard layouts

Keyboard Mapping

You can connect keyboards with different keyboard layout, but you have to set the correct mapping so that Ubuntu knows which letters you intend to type. So you select the keyboard mapping for the language you want to type. Technical details here. We have to tell Lubuntu to which keyboard mapping to use. The simple way to do this is to launch Lxkeymap (under Preferences.)
If you want to switch between keyboard mappings, you need to add a setxkbmap command to /etc/xdg/lxsession/Lubuntu/autostart

To switch between two keyboard mappings with the control+shift keys, Open the terminal and

echo '@setxkbmap -option grp:ctrl_shift_toggle "de,us"' | sudo tee -a /etc/xdg/lxsession/Lubuntu/autostart 

If you would like to use a panel applet to switch between keyboard mappings, you can right click on the panel, select "Add/Remove Panel Items". Next click "Add" and select "Keyboard Layout Switcher". We're not done, we also have to add a setxkbmap command.

echo '@setxkbmap -layout "fr,us"'|sudo tee -a /etc/xdg/lxsession/Lubuntu/autostart

If you want to add another keyboard mapping like German, you can:

sudo leafpad /etc/xdg/lxsession/Lubuntu/autostart

And add ,de after the ,us which is already there.
You will need to reboot or logout before your keyboard mapping switching is configured.
You can find a list of codes on the Pandora OSwiki.

Here is info about the autostart process.

Keyboard mapping for 13.10 and beyond

Since Lubuntu 13.10, the method to choose and toggle keyboard layout has changed. Indeed, lxkeymap application is no longer installed by default, and we have to use Keyboard Layout Handler instead, a plugin for lxpanel.

On Lubuntu default installation, Keyboard Layout Handler appears on the right of the panel, near volume control. It displays a box which describes the current keyboard layout (for example, “US”). To modify keyboard layout settings, right click on it, and choose « Keyboard Layout Handler Settings ». Here you can make some modifications.

By default, the option « Keep system layouts » is checked. Uncheck it to customize your keyboard layout.

Keyboard Model

Here you can choose your keyboard model.

Keyboard Layouts

Here you can choose a layout. You can add or remove keyboard layouts. You will be able to toggle between keyboard layouts you selected. You can choose priority between layouts with « Up » and « Down » buttons.

Change Layout Option

Here you can choose a shortcut to toggle your keyboard layout. By default, it is « shift_caps_toogle », which meaning that you can toogle between your keyboard layouts by using « Shift » + « Caps-Lock » shortcut.

Show Layout as and Panel Icon Size

Here you choose what the plugin displays in the panel. By default, it is an image which is well-integrated in Lubuntu ; but you can choose your own custom image. You can also choose to display a flag, or a simply text.
